Mariana and Ricardo have a lovely home and the place is comfortable and clean. In fact, I had the place to myself almost the entire trip. They seem friendly and kind, though I hardly saw them.
I certainly recommend staying here as the location is ideal and they've done such a good job decorating their flat. My only recommendation would be to make plans with Mariana far in advance as she has a busy schedule and can be a bit tricky to get a hold of. Otherwise, I had a wonderful stay.
