Great location but don't see the value for money
Hotel location was excellent, hop onto the BART from the airport to Powell station and the hotel is just a short walk (3-5 min) away. A few blocks from Union Square, Macy's, major car rental companies and Chinatown, Parc 55's location can't be better. 
However, the hotel charges for everything that a modern traveller would need - USD15++ for wifi, no breakfast included, no international adaptor, no drinking water provided and limited bathroom amenities - made me feel that this hotel is not moving with the times. 
Most importantly, there were plenty of homeless people along Market Street and around the hotel areas which made the location a lot less friendly after sundown.
