They stay at Renés flat was one of the best in my whole airbnb history. The room is very spacious, the bed is huuughe and we even had our own little coffee machine.
The flat is very spacious as well, the kitchen well equiped. If you are not a cooking person, no worries, the flat is perfectly located in the middle of Colonia Roma with plenty of excellent bars, restaurants and taco places just around the corner. Also its a very safe neighbourhood.
René himself is very friendly and attentive host. We felt almost like home. I would definitely recommend a stay at Renés.
