Friendly people, nice room

Loved our stay here! We were in room 501 and had a living room of which we opened the window for fresh air. The small details (decoration, wine and cheese, super friendly staff, good coffee at breakfast) made it a great experience. Also the location near Union square is great.

Poor architecture and ventilation leads to bad nights of sleep

Stayed here two nights. There is a lot to like here: nice staff, good location, little happy hour (wine selection very bad though), ok breakfast.

But here’s the rub: first the building which appears to have been built in the 1910/20s based on the door jams is one long hallway on the left side and a row of single rooms on the the right. The necessitates the room rather than being designed as long from the door to be wide and the bed to be positioned 5 feet from the hallway door. In a modern hotel the bathroom would sit there and act as a sound buffer. So all night long you hear people talking and walking back and forth. This is especially accurate in you are a lower room number—I was 301. So I was the first room into the hallway and had to listen to people wake me up all night long and morning. Not a good nights sleep at all.

Second, as someone else mentioned, there is no ventilation. Zero. My room was hot (maybe 78) and even though I had the thermostat turned to 65 nothing. No air flow at all. And the room smelled and is dank/musty.

Lastly just one elevator. So one morning at 7am I waited for over 5 minutes as the maid occupied and blocked the elevator for every floor cleaning out the previous nights cookies jars. Not optimal.

For the money I think you find way better.

Overall good. Some cautions though about ventilation and street noise. Late Maid Service.

We stayed for three nights this past week. Couple in our 60's. Hotel is very well located. King suite decent value for SF. It was warm in SF and the room has no ventilation other than heat. Every window in the hotel was open including ours because it was warm in the hotel. There was lots of street noise even when we closed the windows. Early AM trash pickup was particularly loud with bottles being dumped. I am used to urban environments but the windows definitely old fashioned! Also the maid service was very late. We left at 830am and returned at 430pm and was not done. The hotel staff very spotty. The manager was excellent but was not there all of our days. Other front desk staff knew far less than us and much less friendly. One recommended a restaurant a few doors down the street for lunch that was only open for dinner.
