I always book my hotels in the Gaslamp through Hotwire and get a great rate on a 4-star in the area. This hotel was neat because it's dog-friendly and they don't charge extra to bring your pet. Valet parking is $38/night, but if you can find a spot in a lot nearby (and don't mind walking a little) you can save some money.
I don't believe they have a pool or jacuzzi and some of the other 4-stars that I've stayed in do. We could also hear a dog barking durning the day in a room near ours, but it didn't bother us and we were out and about most of the day/evening anyways.
