We were in room 315, which had a pvt bathroom. Overall, our stay of six days was quite wonderful, and I would highly recommend this hotel for anyone who is considering a future stay.
The host was very quick to respond to all my inquiries before the trip (even at 11 pm!). This place functions as a boutique hotel/motel. You can catch airport shuttles to/from the hotel at $14 each way, which I thought was very convenient. All the staff we met were very friendly, professional, and well trained. There was someone at the front desk through the whole day, whether it was early morning or late at night.
The location is unbeatable for the price, since it is right in between Union square and China town. You can catch city buses or the numerous town tours all within couple blocks of this place.
The room was clean in general. I felt the bed sheets/linen could have been cleaner. In particular one pillow case had various spots on it, while the rest of the bed spread looked like the sheets were not changed after the last occupant.
There was a shared iron/ironing board, a coffee maker, a microwave, and laundry machines next to the lobby area. As someone who traveled with a professional conference to attend, I felt an Iron within the room would have been convenient. The older model TV inside the room wasn't really serving any purpose, with the reception being not too good. Mini fridge was a useful thing to have there. Maybe in the future as they keep renovating this place, they can place a microwave on top of the mini fridge, which wouldn't take much money/space to implement - yet add value to the room. The high-speed WiFi within the hotel was great (I would say even faster than some bigger hotel chains WiFi I have experienced).
We did not have to use any heating during our stay, since the weather was optimal. I do agree with the other reviews that the bath/shower could be a touch warmer. But I am sure they have to think of balancing the cost of water heating at the price they offer (at least for now).
The sounds from the hallway does get in to the room, but in general I thought the room was quiet considering the area the hotel is in. Particularly at night time, we didn't experience any disturbing noise from within the hotel or from outside.
Finally, hope this review is useful to someone in deciding whether or not they want to stay at this location (and to the hosts in improving as they keep renovating the hotel). I personally would definitely stay here in my future travels to SF, primarily based on the exceptional location and the fantastic staff they have.
