Just returned from two nights in San Diego at the Hilton Gaslamp. The hotel was very conveniently located and the staff were very pleasant. We had two rooms and they gave us complimentary diamond upgrades to a loft double room and a large (750 sq. ft) loft jacuzzi suite. The rooms were excellent, but if you do not like noise, this would not be a good location especially on the weekend. The Hard Rock Hotel is across the street and it is very loud. Ear plugs are provided in the room, but they don't do much to curtail the noise. As a diamond member we were given two free breakfasts per room per night which could be used for the buffet or the ala carte menu. Overall I was not impressed with the food, except for the lox and bagels which were fantastic. The internet was free and the service was excellent. If you are looking for a decent mid range hotel in the gaslamp district that is very convenient to trolley service, this may be a good fit.
