We stayed here for a 6+ week stretch. The apartment was adequate but did not meet expectations (especially for the price) TL;DR: Great for one or two nights, but would not recommend for a longer stay.
Be aware of: (1) Little natural light (2) Lack of Sound privacy (3) Less than stellar kitchen (4) No real closets

Location:
The apartment is located in the center of downtown San Diego, steps away from the heart of the Gaslamp district. Bars and pubs abound, and there is lots of activity in the evenings, especially on Thursdays through Saturdays. Downtown San Diego is unfortunately home to many homeless people, so it is nice to not have to walk far to get to the nightlife of the city. The door code to get into the building in addition to the lock on the individual apartment made us feel safe and cozy inside the building. There is a comedy club next door, so it can be a little loud in the evenings, but the shows are usually done by around 10:30, so they did not keep us up at night.

Interior:
The apartment has three “bedrooms,” but none of the bedrooms are fully closed off. There is no sound barrier between any of the rooms. The downstairs bedroom nearest to the entrance (Room A) has four walls and a door, but no ceiling. The downstairs bedroom farthest from the entrance (Room B) is a nook under the stairs with little to no privacy. The upstairs bedroom (Room C) has a door, but only three walls. So, you can hear everything that is going on in the apartment from any of the rooms. You can’t see into any of the bedrooms from the other rooms, so there is visual privacy, just not sound privacy. It seems like this wouldn’t be an issue for a night or two but was less than ideal for a long-term stay.

The dining area and living room area were both lovely. The TV comes ready to go with Netflix, HBO, Hulu, and others (although you have to use your own login credentials to access the sites). The in-unit washer & dryer were great.

The kitchen is understocked. Don’t expect to cook regularly unless you bring your own kitchen equipment (eg no medium/large pan, sharp knife, etc) . The stove is an electric stove that we were never able to get to the right temperature (there are no markings on the temperature knobs, so you have to guess), and the burners are crooked, so your pot or pan is always leaning to one side or another. There is a dishwasher, though, so that’s a plus.

There was little natural light in the apartment except for in the mid-morning, and Room C especially was always quite dark. We ended up buying some extra lamps to use in the evenings because the lamps provided left the apartment rather dim.

There isn’t great closet space in any of the bedrooms. There are hooks with hangers on them, but the hooks are right against the wall so you can’t really keep more than a few things on them (we put hangers on the balcony railing for most clothes)
Overall, the apartment was comfortable and well-located. I would recommend it for a one- or two-night stay if you’re okay with limited privacy.
