We had a great stay!
There was some miscommunication about our arrival time, which resulted in us sitting on the steps in front of the house, tired and sweaty. We tried calling Grisula, but she didn't pick up the phone. With the help of a very friendly neighbour, we finally managed to get hold of Pablo, who apologized for the misunderstanding. After that, we had a great stay. The place is near several subway stations and the neighbourhood is full of shops and cafes. I'd definitely recommend this place!
