Charming, clean place. My husband and I enjoyed our visit. It is up a hill and then 3 floors up, so be prepared!
The flight from the U.S. gets in around 9:00 a.m. and check in isn't until 3:00 p.m. There is a luggage storage place fairly close by, but we were tired from the overnight flight and just wanted to get settled in. If no one has the place booked for the night before, Mariana will be accommodating and let you check in early - but you can't count on this.
My suggestion (and I wish I had thought of this before we booked) is to book the night before so you can go directly to the apartment from the airport.
Also, make your life easier and call for a Uber ride from the airport. (You catch the ride from the upstairs section of the airport.)
