I was in San Francisco for a convention and stayed at the Hotel Rex. I've stayed in this hotel twice before and always end up coming back when I am in SF. The location is really convenient to BART/MUNI, Union Square, Convention Center, shopping, etc. Unlike the formulaic major chain hotels, the Rex has old world charm and friendliness. Other hotels are frenetic and businesslike. The folks at the Rex are professional yet friendly and the atmosphere is calm. The rooms might be a little dated, but the general literary theme of the hotel makes up for that. Jeff at the front desk is very friendly and helpful. Thanks for another great stay, Hotel Rex!
