We had a pleasant stay there, the location is good, the apartment as expected from the pictures and good communication with Carlos or Silvia.
We didn't put 5 stars because a lot of the basic things we typically find in Airbnbs were missing:
we didn't have enough towels, insufficient toilet paper, missing basic ingredients to cook such as sugar, oil, etc...).
Moreover a few things in the place were broken, such as the moka pot, the windows and blinds that don't close properly, a few lamps.
Silvia was really nice and offered compensation for the money we spent on the basic necessities we bought and left there, which greatly improved our overall perception.
