Cute boutique hotel
The hotel was very cute. There is no air conditioning because of the climate in SF, so we left a window open during the day to let some air in, otherwise it would've been too hot to sleep comfortably. They do have high powered fans to try to mitigate this. There is heat in the room, but we didn't need it in June. The bed was decently comfortable. The sheets could have been softer, and the pillows could have been more comfortable (for different types of sleepers). The location was great and walkable to all the highest end stores you could want. Parking was around the corner (3rd party but close to the hotel). It took a while I'm the morning to get our car because lots of people who work downtown bring their cars into the garage to be valet parked at that time, so be aware of that when leaving the hotel with a car.

Consistently excellent
Excellent as always - I've been coming for a long time. Service is consistently excellent. Great location. I miss the breakfasts and afternoon socials. It'll be great to bring them back.

Respite Amidst the Pandemic
We enjoyed our stay at The Inn very much. It all started and ended with the warm welcome and graciousness of Jorge. The entrance was narrow and unassuming but don’t be fooled. Inside you’ll be pleasantly surprised. As soon as we got in, we felt right at home; it was warm, quiet and clean. The receiving area was cozy. I loved that the outside of the hotel and street was also clean and felt safe. Check in was efficient. We even got a room upgrade, for which we were thankful. The suite was clean and well-appointed. The bed was comfortable and provided us with restful nights. The portable heater was a god-send. There was a purified water dispenser which is in keeping with the eco-friendliness we desired. There was Peet’s coffee every morning at the 2nd floor; a great way to start the day… as long as your day started early. It’ll usually run out by 10. I highly recommend this place and would stay here again if I’m back in the area.
