We had a great stay at Sandro's apartment. We were greeted by Lalo's mother who handed over the keys with no problems, there was also bottled water and pastries which was a lovely treat. The apartment is in walking distance to lots of great restaurants and bars, and a 10 or so min walk to the Metro. Only downside for us was how light the apartment is at night, due to sheer curtains.
Overall great stay and highly recommended.
