Michael's place was very clean and in an excellent location to explore San Diego. It is not a luxury location, however the convenience and price cannot be beat. The kitchen is spacious for group dinners and the house was quiet and welcoming.
The house seems to be staffed by helpers to check guests in and do cleaning which worked well for me. (It is not a room in someone's home, but more of a house full of separately rented rooms.)
I would recommend it for a short stay, vacation with a group of friends, or if you want to be walking distance to many of San Diego's attractions. It was not a problem for me, but if you are very sensitive to loud noises, it is very close to the airport.
