Old Town Inn San Diego
Nice place, good helpful staff, clean, a little out of the way, but close to public transportation, the airport & Old Town. I'm not sure I'd walk in the area at night, but we had no problems.
I'd stay here again if I get back this way, probably would be better for someone with vehicle, we walked and rode bikes. My only complaints, the bed was too soft for me...and no fault of the hotel, but someone let their dog keep barking while they walked it.
