Molly was great to work with. She was quick to respond to questions before and during my stay. We needed a pack n play and she made sure there was one in the house when we arrived. I actually booked the wrong dates and didn't realize it until we were in San Diego. Luckily no one had booked the day right before us because Molly changed our dates without any trouble and with no extra charge.
The house itself is definitely small but we pretty much just slept there so it didn't make much difference to me. My 2.5 year old loved the bunk beds and the butterfly decals on the wall. It was nice to have beach towels there so we didn't have to pack them. The kitchen had everything we needed for making breakfast. Everything was clean. The parking space is narrow so I don't reccommend getting an SUV if you are a timid driver. We had a jeep and the spot was wide enough but we were definitely nervous about hitting poles everything we pulled in or out.
The location is great! Walking distance to two beaches. 15-20 minutes to the zoo. 15 or so to sea world. And walking to coffee shops and restaurants. Molly put together a nice list of restaurants in a binder in the house, it's a great place to start when exploring the neighborhood.
