Excellent base for Gas Lamp, Little Italy and Balboa Park. We quickly got used to the air noise (pretty cool to see the planes so close up) and neighbors were all quiet - people appeared to come and go from the other units so it might differ!
Off- road parking was difficult when there were 3 SUVs so we ended up parking on the road (free spaces all down one side of the street).
Clean and well-equipped but hot water took ages and could do with more furnishings (sofa and bar stools look cool but not v comfy and only 1 small table which we ended up using as a coffee table and bedside table and lack of lamps anywhere)...it is very minimalist! As we were out most of the day, this didn't matter but if you're looking for a place to hang out, it's worth bearing in mind.
