Former aristocratic villa on the island of Ischia with two thermal pools, a private beach and a rooftop restaurant

The Lowdown

Fronting a wide private beach on the east coast of Ischia in the Bay of Naples, Hotel Mare Blu Terme is a boutique retreat in a former patrician villa. Fully revamped in 2011, the salmon stucco exterior, tile balconies and humongous pool decks are a modern take on classic Mediterranean architecture. The 40 spacious guestrooms are decorated in soothing gold and blue tones, with terra-cotta floors, chunky country-style furniture and brightly colored flower arrangements. For added space, book a suite or a Deluxe Room; both feature private terraces and balconies with sea views. Soothe aching muscles in the outside thermo-mineral pools, or opt for a mud bath, a Turkish bath or a hydrotherapy treatment at the hotel’s state-of-the-art spa. In the evening, chill with a glass of prosecco amid palm trees and bougainvillea at the poolside bar, or dine on fancy Italian fare at the rooftop restaurant. Live piano music adds to the elegant, romantic vibe.

In the Area

It’s a short walk across a stone bridge to the Aragonese Castle, a medieval fortress built to defend Ischia from marauding pirates. Admire the views, then hop a taxi to nearby Villa La Mortella, where you can stroll five acres of subtropical garden surrounding the former residence of English composer William Walton. There are classical and jazz concerts held here from April to November. Ischia has been used as a location for films as diverse as Cleopatra and The Talented Mr Ripley, and every July Global Fest celebrates the island’s unique place in film history.

Myself and my husband stayed at the Mareblu for a week with voyage Privé.We we were taken to room 237, which was very small , bathroom even smaller, couldn’t fit 2 people in ! , lovely view out of window though. We lasted 2 days and asked to be moved to another room. We were given 235 which was bigger but view not so good. Breakfast was average. Hotel was very quiet at this time. Our saving grace was exceptional bar man Luigi , who was friendly and helpful and could speak good English. The sister hotel across the road, Miramare Costello which you can also use has lots more going on and has more character.Lots of little things wrong ie no tea /coffee facilities in room. We enjoyed our stay but thought it would be a lot better.

What shade of blue is heaven?

It is a serious question: What shade of blue is heaven?
From the moment we showed up (way too early due to ferry schedules), we were treated with nothing more than the utmost respect and deference. The people of Hotel Mare Blu Terme take their business very seriously and are very proud of the experience they offer, and rightly so. This was one of our best stay in a property of this caliber. They maintain a very, very high standard in almost every aspect of their property. Staff is plentiful and eager to assist; always with a smile I have to add.
When showed to our room, our jaws dropped.
The room, small but well appointed, had a wrap around terrace on the corner of the building. The sea was a brilliant shade of blue, competing with the sky and a full view of Ischia’s landmark, Castello Aragonese. Absolutely stunning.
The property is very clean and extremely well maintained. The only unsatisfactory part was the « thermal » pool. It didn’t feel like the same attention given the rest of the property had been lavished on it. It felt a bit « swampy ».
However, it could be that they are working on it as the exterior pool and other areas were being worked on continuously. The spa is great, massage was fantastic.
All in all, we really enjoyed our stay and hope to visit again. We have stayed in Ischia in the past, visiting our friends, at a property offering better «Thermal Pools » but certainly not the level of hospitality of Hotel Mare Blu.
Can’t wait to see that shade of blue again...

The hotel is very clean and quiet at night. Its a 15 minute leisurely slow stroll to the main town shops and port (or 16 euro one way in a taxi - expensive), or 10 minute walk to Ischia Ponte and the castle. Loads of places nearby to eat with various price ranges. Turndown service in the evening. Hotel restaurant is good with attentive service from Maurizio and his colleagues. Breakfast spread is fine, plenty of choice. Front desk helpful with issues such as transfers to airport and good language skills. We stayed a week and the room was spotless... not big.. but for us it was a place to sleep, shower and get changed. The rest of the time we were out. Bar was good, with comprehensive cocktail list done by Luigi. We went to Capri for a day and were glad at being on Ischia. Not as expensive or crowded. Get a one day bus pass for 4.5 euro to go around the island, hop on and off as much as you like.

The best place to stay on Ischia!!

Hotel rooms are like a box of chocolates, you never know what you might get! No, you don’t spend all day in your hotel room, but if you find yourself in rooms 273 or 236 with your own South facing terrace, complete with Balinese bed, overlooking the awe inspiring Castello Aragonese, you might want to spend all day there! How we were privileged enough to find ourselves in this wonderful room is beyond me! Thank you Mare Blu!!

Special thanks to all of the wonderful Staff. Roberta communicated very well by email with us regarding our transfer to/from the Airport. Allessandro made sure our drinks were continually full when we sat by the pool. Luigi served us at the bar. Not sure of other names, but each and every one of them made us feel welcome. They remembered which room number we were in whenever we ordered anything, or needed our room key.

Toiletries provided in the room, as were dressing gowns and flip flops. Maid gave us chocolates every evening. We had a fridge. The only downside was no tea and coffee making facilities in the room so we took our own travel kettle. The bed was big and comfortable. Wi-fi was good. Unfortunately the air con can be a bit noisy.

Loved the way the hotel grounds were laid out. Lots of places to sit, whether to sunbathe or to just be quiet and read. Relaxing background music. Thermal pool was lovely. We had back and head massages by professional spa staff. The main pool was lovely. And just across the road at the sister hotel, we had full use of the beach and sunbeds. Also their pools (indoor and out) Again, plenty of places to sit, whether it was sun loungers, or the more comfortable easy sofas. It was all so very relaxing for us.

Breakfast was mainly continental with scrambled eggs and bacon on offer.

The hotel is about 20 mins walk to the main port, which takes you past some lovely shops to look in. It was great that a festival with fireworks was going on whilst we were there. Castello Aragonese is just a short stroll away and a must to see with splendid views all around. We took a 3 hour taxi (guided) tour of the island. We visited Giardini la Mortella (botanical gardens) which we can highly recommend. We had a boat trip around the island. Also an afternoon trip across to Procida. We got a taxi up to Mount Epomeo where one of us had a horse ride to (almost) the summit while the others walked alongside.

There are loads of places to eat and drink within walking distance. Mostly it is all flat, but the roads and paths are cobbled and uneven in places.

Ischia is a delightful island to stay.
