We stayed in the room for 2 nights, and were really impressed. The room was clean and cozy, and there was easy self check-in. The location is very convenient, being right downtown and close to the Gaslamp Quarter and Little Italy. As some people have mentioned, the noise from the street is quite loud, as it would be in the downtown of any big city. However, we didn't have much of an issue with it at night, and slept well even without earplugs. The bed was really comfortable, and the bathroom was clean and well-maintained.
The only downside of this place is that the parking in the area is expensive, but we did know that beforehand. Overall, I would highly recommend this room if you want to explore downtown San Diego.
