Service Service Service!
We loved this hotel - wonderful staff, nice quiet location, comfortable beds... the positives go on and on!
The location is nice, in between Union Square & North Park. Not really walking distance to Pier 39, but public transportation in the city is easy!
The service is wonderful at the hotel, willing to do whatever you need! I wanted to order Pizza to the hotel room one night, they sent menus to my room. We needed information about a tour we were taking, concierge was accessible easily and knowledgeable! 
I would certainly stay here again!
