I want to start by saying that Fernando, our host, was excellent. Very responsive, dropped off some dish towels and a bath mat during our stay (both of which were absent on arrival), and helped when the internet went out and the door lock seemed not to be functioning correctly (this was user error).
The location, just south of Carlsbad Village by about .8 miles and across the street from the beach, was amazing. Our family enjoyed the walks to the Village to get dinner at Gregorio's, ice cream at Handel's and breakfast at the The Goods and Super Donut.
The property itself was, as some other reviews have described, musty in odor and in need of updates. There was some visible rot and deterioration of the wall near the shower beside the vanity. All of the interior doors are in need of repair. The couch in the main living area is rickety and I was worried it would collapse under my weight (I am 6'1" and 200lbs). I spotted various insects inside during the stay. On a positive note, we did appreciate the AC units in the bedrooms.
Overall, we enjoyed the convenience of the location and the responsiveness of our host but would not stay here again.
