The location and house set-up are as advertised. You're truly in the hosts' backyard (the main house windows can see into the guesthouse) and have a living room/bedroom combo, comparable to a studio apartment with a kitchen and bathroom. The washer and dryer are in the guesthouse and were available for use but that also meant the family needing to come in to use them, though that was mainly reserved for Thursday's. On Thursdays a cleaner came to do laundry and cleaned the guesthouse as well, which was great.
I'm a college student and stayed in the guesthouse for a 12-week period over this past summer. Some interactions with the host were weird such as being asked if I was home since the lights in the kitchen were on (I was in fact home) and repeatedly being asked not to run the air conditioner when I wasn't home (LA in the summer isn't cold). Early in my stay I had an off-putting discussion with the host about having overnight guests, since I had a friend living in LA the area that was interested in spending some nights in the Airbnb over the 12 week period. Since I didn't put down for two guests, this request for the friend to stay over wasn't allowed and I was told it would cost $20 per night for any additional guest. I was also questioned about having the friend stay over prior to asking about it. The friend hadn't stayed over, and the host insinuated I was lying, which was a bit uncomfortable.
Overall, the location for me was great. You're right near a main drag of Culver City which has several bars, restaurants, ice cream and a movie theater. About a 15-20 minute drive, and you're at Venice Pier. The stay overall was as advertised on the site, but as a young college aged male it was a bit of an overbearing experience that I'm not sure I'd do again for an extended stay.
