The cottage is very nice and cozy, the patio is great, everything is just as in the pictures. We were 4 people, 2 friends slept on the sofa bed and it worked well. It was great to have the patio to hang out and have a little extra space. The cottage was very clean and everything we could have needed was provided, even good coffee and boards for the beach. Rick was very welcoming but we also appreciated that he gave us space and we felt very independent from the main house.
Quiet neighbourhood, a car is a must. We were attending a conference at UCSD and location worked fine (about 15 min drive), also about 20 min to downtown La Jolla. We didn't have time to explore downtown San Diego so I can't comment on the distance or convenience. If interested in La Jolla area and a quiet and nice place to stay I would highly recommend it.
