I just stayed six nights at Beto's place and could not be happier with my choice. The location is excellent for numerous reasons, and it was spacious and bright and airy (there are two fans in case you're wondering, that was important to me in case it got hot). So quiet even though you're in the heart of the city! I loved that it had a separate bedroom because most of the options in this price range did not. I was a last-minute booking, 48 hours out, and was worried that this would cause me stress but it went smooth as can be because of how fast Beto responded to any of my messages. I was also concerned about a possible language barrier given that this was my first foreign Airbnb experience but I worried for nothing.
Beto went out of this way to help me find the location (I made a subway mistake) and he checked in to make sure everything was to my liking. He provided a lot of little extras like a bottle of champagne (which I neglected to drink), and biscuits and fruit, which made it easy for me to eat in the morning after getting in late.
Overall, EXCELLENT VALUE !
