I stayed at Mariela's studio for a month and loved it. The place is spacious and looks just like in the pictures. The neighborhood is safe and it has very good restaurants all around and the best ice-cream (helado) right across the street. It's 10 min walk from the SUBTE station and there are bus stops all around. Mariela has very good suggestions for everything including money exchange at the best rate possible. She is very friendly and accommodating. I am planning to return to her place soon. I recommend the place highly.
