An hotel for deaf people?
The Sofia hotel is historic hotel in the San Diego down town. Excellent location, close to many city "must sees" susch as Gaslamp, harbor, convention center...
Staff at the reception desk is OK and I have no complaints. 
Advice for the European visitors- you can get power adapter at the reception for free. For coffee lovers you can drink "normal" coffee ( cappuccino looks and taste like real cappuccino) at the coffee shop which is just next door to the main entrance in hotel.
How to explain my title? 
Room is equipped with air condition which is very loud. First night I decided to turn it off, risking overheating, and that can reduce the noise cca 30% but still air ventilation is rumbling all the night! You can't turn that off! If you have sleep disorder or tiny nerves you should stay away from this hotel.
Also I don't like that you can't open the window, even minimally. Problematic is room size like some other reviewers wrote before. 
All together- nice position but small rooms with loud air-condition.
