We had a great time in Mariana's place, stayed there a week. No problems whatsoever. It was a hot week, but in the apartment it was pleasantly cooler and easy to get a good night sleep. Communication with Mariana was smooth and easy. Mariana's mother gave good tips and we enjoyed especially the Casinha Cafe close by. Location for us was good (didn't want to stay in more touristic area), it was easy to get to all the places from there. I would recommend staying here:)
