I've stayed at some 20 different airBnBs over the years, and this one stands out as the worst overall experience. The only nice thing I can say about it is that it is relatively inexpensive and located in the heart of downtown San Diego, within walking distance of many restaurants and bars. When entering the building, I was overwhelmed with a noxious odor that only got worse as I walked the halls and entered my room. I can only describe it as a cat litter box needing to be cleaned. The listing made no mention of the kitchen being shared among all (40 or so?) rooms and the room was smaller than the cheapest hotel room I've been in. The place is essentially a flophouse.
