Great location in Del Mar and a very clean place! Great bed linens and plenty of towels/soap/etc. Easy walk to beach (~20min) and drive (~5min). Also, very close to restaurants/bars/grocery stores. Karl greeted us when we arrived (they live in the downstairs space). He was very attentive and responsive.
We worked from this location for a week and the internet was solid. Fully stocked kitchen was appreciated. Washer and dryer were newer and supplied w/ detergent in the garage. [NOTE about the Garage]: The garage is a very decent size... however, we couldn't park our F-150 truck in the garage (although our truck is stock [no lift], there wasn't enough clearance), so we had to park on the main street. It appears to be a pretty safe neighborhood and we had no issues parking our truck there all week.
There isn't A/C in the unit and it was humid and hazy throughout the week, but we were able to keep the windows open most of the time and the unit has fans that help circulate cool air.
Overall, we would gladly stay there again.
