No Aircon !!!!

The room is boiling .there is no Aircon... And they never said when I checked in. It's stylish and nice BUT WE NEED AIRCON BECAUSE ITS BOILING . and it is outrageous to charge 350.usd for a room with no Aircon. They brought a portable one that sounds like a lawnmower

We stayed for 4 nights in this hotel and it was wonderful. The room was was v comfortable, the breakfast was plentiful and varied and there was even complimentary cheese and wine in the early evening. The location was perfect for exploring and despite its central location surprisingly quiet. Finally the staff were friendly, welcoming and v efficient. A special mention should go to the manager Ann who was simply amazing,


We loved this hotel!! We were upgrated and our suite was beautiful, with tons of light, a super comfy bed with high quality sheets and an amazing bathroom. Hotel staff is very friendly and profesional. Special thanks to Gustavo for taking care of us!!!
