Staying at Mariana’s place was a very pleasant experience. My top concern is always safety, and I felt safe in the locked building that requires a key for entry.
The apartment was exactly as pictured, very clean, and in a convenient location that is about a 15 minute walk from the main square and 25 min drive to the airport (when I took it anyway, as traffic fluctuates).
Mariana was very prompt to respond to any questions I had, and Rosario was equally nice and hospitable.
Overall, I would recommend this place!
