Unfortunately my stay did not go as expected because I arrived and the AC unit listed on amenities was not blowing cold air. I contacted the owner and she let me know she was aware of the issue, but did not inform me prior to arriving. For the first two nights I was provided fans but no AC cooling alternative and the temperature in the loft (where the bedroom is) reached 84 degrees. On my last night the owner was able to bring by an alternative AC unit that did help with the last night to cool the space. Moving forward I imagine the new AC unit installed upstairs should keep the space cool for future visitors.
Beyond that, the space itself is very nice and clean; the fridge had ice trays and condiments for convenience and the kitchen was well stocked with utensils and appliances. The little desk area in the loft has a nice view of the hillside and the tall windows at the top of the space had really nice views to look at. I will mention those windows do not have coverings so for those where sleeping with light may be an issue, keep in mind to bring eye coverings.
The location is within a nice, safe neighborhood in Rancho Bernardo and was quiet. Overall if I can confirm the AC is working ahead of time, I would definitely stay again.
