Katya has a ton of useful tips to suggest good spots in San Diego, so feel free to ask her.
The studio is clean and looks artist. there are a fridge and a tea kettle to keep maybe your water, desserts, and other drinks. Beds are comfortable to sleep on, and there are some shower towels if you plan to go to swim in the beach.
-Parking spots are on the street, but a bit tight at night. So my recommendation is parking the car in the afternoon as latest and go the night pub and bars by Uber/Lyft because it takes 15 minutes drive to there. The bathroom is a bit small, but you can be fine to take turn using it, there are soaps, shampoo and conditioner provided in case you forgot. And dryer, iron are available.
