We did not meet Juan, but his friend Marcela welcomed us (although there was a language barrier) - Juan called us on arrival and explained everything we needed to know. The location of the flat is great (nearby is a metro, an amazing park, beach, supermarkets, restaurants etc). We had a comfortable stay - our only complaint is the squeaky bed! Overall Juan was very helpful, gave us great recommendations, and replied to messages promptly. We recommend staying here!
