We (4 con professionals) stayed at Ronnie's bungalow for the week of SDCC. It was a short drive to the Gaslamp or one of the train depots so it was pretty convenient. In hindsight, I would have preferred a location within walking distance to the train as parking was ridiculously expensive each day.
Ronnie's bungalow was cutely decorated and while an older home, clean and comfortable, especially the outdoor deck. Overall the experience was fine, but I would definitely say that this place was very small and would comfortably fit a couple, 3 was do-able but 4 was a definite squeeze especially if you aren't all already coupled.
IMPORTANT NOTE:
Dependent on the season you visit, and the weather, this location is right under the main flight path for the airport and is VERY audible in the bungalow from the hours of 6am-11pm. You might want to check with host to see what the flight patterns during your stay might be. There isn't a lot in the immediate area for food that we saw (other than a 7-11) so we ate mostly in the downtown area. The bed and couch were both rather hard, but surprisingly not uncomfortable. Everything else was nice, wifi was very useful and easily accessible. I did not have the opportunity to meet Ronnie in person, but we were fortunate enough to meet some of his neighbors/friends upon exit and they could not have been more kind or sweet people. Absolutely the salt of the earth and I was sorry that I had not met them sooner. Overall very decent stay.
