I stayed a week at Mariano’s place and everything was great! The house is in the very center and close to several metro stations. Nearby there’re many shops, supermarkets, restaurants. Though it’s quiet at nights so you will sleep well ;) the WiFi is pretty good for working. And the most important thing for me was that Mariano changed the frying pan for a new one when I asked, so it was a pleasure to cook :) gracias! I would be back if I have a chance.
