The Residence Inn by Marriott was a good stay for vacationers to stay at: Close to numerous attractions, restaurants/bars, entertainment venues. We personally hit up False Idol (tiki bar), Maritime Museum of San Diego, USS Midway, Vistal Restaurant (inside InterContinental hotel) and The Rady Shell.
As a room, hotel in itself as a resident, no real problems except for the slight sewer smell that emanated from the sink after running the water. That is easily fixable, I assume.
Pros: Location, outdoor patio bar, free continental breakfast, great views.
Cons: The minor plumbing issue, above.
