Jon's place is super clean, very central and super modern. It only takes you 10min to get downtown by walking and everything except the beach is really just in walking/scooter distance. We would definitely recommend staying at his place, but parking was a bit tricky as it was only free 2 hours at a time and from 6pm-8am, but that is the case all over San Diego. Nevertheless, Jon was super helpful with solving the parking "problem".
