4.5 stars, but Airbnb doesn't allow fractional ratings, so I rounded up.
1) Backyard - incredible, resort-like. The pool, water slide, zipline, trampoline, large grassy field to run around, outdoor dining, fire pit. Everything you'd want, especially if you have kids. We were able to have a perfect bday party for our 6-year old, sheltering-in-place.
2) House - the house was big enough to fit 2 families, but it is a bit older and outdated compared to the star of the show - the backyard. Kudos to the host family for scrambling to get all 6 of them out with less than 24 hours notice, but per the description, definitely some imperfections as it's their primary residence.
3) Location - great location near Mt. Soledad, and a quick drive to multiple beach options, great food options.
4) Host - Adam was super responsive, communicative, flexible.
