I had a great stay at Michael's treehouse! The outdoor shower was wonderful every morning and the common areas were very nice to sit at in the evening. The room is small but perfect for sleeping! Some mentioned the planes, and you can definitely hear them, but they didn't bother me at all during my stay. I was able to enjoy a nice walk to the San Diego Conference Center every morning (about 30 min). I would definitely recommend staying here for a unique and affordable experience in San Diego.
