Booking with Franz was super easy, I was coming to town for a convention located on Hotel circle and his place was perfect. I didn't spend much time there but the room was extremely quiet and comfortable, which was just what I was looking for. Also it was great to have a private bath so I didn't have to disturb the other guests when I got back in the wee hours of the night.
The location was very easy to find, not far off the 5, and off of pretty major streets. Parking was generally super convenient, except the one night I didn't get there till after 2am I did have to hunt a little but still wasn't too bad.
Overall had a great experience, it was a fantastic way to be introduced to airBnB. I will definitely be checking back next year when I come back to San Diego
