Me and my friend had two nights at Rocio and Nicolas place and it was AMAZING! Beautiful apartment, very clean and in a lovely neighborhood. Rocio and Nicolas are superb hosts, gave us so much good information, they were so easy to get in contact with and made our stay very pleasant! We couldn't ask for anything else, this is one of the best airbnb experiences we had. I wish we could have stayed for longer, but next time when in BA I'll def stay there again!
There is a reason why this place is usually fullybooked, it is everything you wish for in an airbnb!
