Public transportation is not very good in San Diego, but luckily Uber/Lyft is very cheap. The house is only a $7-12 Uber ride to the Gaslamp district, $15-20 to Pacific beach, and $12-17 to/from the airport. The room will have a bed, a fan, a stand and a tall shelf unit that can be used to store your clothes. I will provide a towel and some small toiletries. The living area has a large tv, couch and an exercise machine.
The room has a desk, book shelf, TV, dress A/C and a lock on the door.
Very quite and calm neighborhood.
Public transportation is bad in SoCal, but Uber is cheap. I think that is the best bet!
