Great location and beautiful unit! My family and I were in La Jolla for a wedding at La Valencia so it was an easy trip into town (~1 mile walk or short Uber!)
However, we did have a couple of issues throughout our stay. The first was a bit awkward - we had our family of five at the unit for the duration of our stay, but prior to the wedding, invited 5 other cousins over for approximately 30 minutes prior to leaving for the wedding so that we could share Uber rides to the venue. Within about 20 minutes, I received a text from the host asking if I was having a party and to shut it down immediately. It was very awkward and we felt as if we were being watched or spied on, especially since we weren't doing anything loud or obnoxious. Fortunately we were heading out the door so it didn't cause any other issues, but that made us feel a bit uncomfortable.
The next issue occurred with one of our family members getting completely locked out of the unit at night, as the people on the first floor unit dead bolted the entry door. The shared entry wasn't an issue at all until that had happened. However it does get a bit loud because you can hear people entering in/out down the stairs.
Overall, great stay, just the above issues were unfortunate.
