Absolutely brilliant in San Francisco!
I booked this hotel based on TripAdvisor reviews and it was absolutely the right choice. 
First : The location. It is right beside Union Square, a 2 minute walk from Market Street where shops and all sorts of public transport possibilities abound. Avis rentals are 2 blocks up the street. Dylan's tours pick you up from outside the hotel. Numerous eateries on all streets around the hotel.
Second : The hotel is really charming. Kind of what you'd expect an old house to be. Yet with modern functionality. Every evening wine and cheese is served on Levels 3 and 5 from 5 to 7. Good wine and gives you a chance to bump into fellow travellers. Or take your glasses to your room. Breakfast is served each morning in the same locations. Each floor has tea kettles, numerous tea varieties and fruit for whenever you need it.
Third : The staff are just amazing. Ever helpful with absolutely everything. Always a pleasant smile and a short chat, should you feel like it. Warmth from the frequent chilly San Francisco weather.
As a combination it is hard to beat and I strongly recommend this hotel to any traveller to this lovely city.
