This spot is very central for downtown San Diego and is walking distance to the convention centre. It's also near many metro stops; getting around is a breeze. The listing pictures are an accurate depiction of the room. Not shown is a communal kitchen, laundry room, and patio. The hosts were very communicative and responsive, easy to talk to.
Keep in mind that this area is downtown, and it is pretty lively on weekends. The spot is next to a nightclub and the window is a bit thin so street noise also comes in; earplugs fixed this issue. Similarly, there is a lamp post outside that illuminates the room all night so if you're a light sleeper, a sleep mask is a must.
Overall, lovely Airbnb with great communicative hosts. Central location, and check in and check out instructions are clear.
