We had a good overall experience staying at Mario's house. It has basic amenities and is your standard AirBnb crash pad. It's walking distance to the Gaslamp district which is a blessing and a curse. The neighbors in the next door unit share the entire left wall. Two different groups were parting hard until the sun came up. It didn't bother us too bad but if I was there with my family it would have been bad. Also the area is full of homeless people. I mean everywhere. I didn't feel super safe walking around but we took Ubers everywhere and didn't spend a lot of time in that part of town. It's a great deal and if you are young and like to party then this place is perfect for you. I would probably stay in Ocean Beach next time I visit San Diego because I really liked that part of town.
