I did not get to meet Matias, but he was extremely welcoming throughout our communications and checked up to see I had settled in ok. His friend Jaime let me in and showed me about the apartment which was great. The apartment is nice and clean and comfortable (just like in the pictures) with a great shower and wifi and all the extra conveniences you might need. The apartment is in a great location too, lots of restaurants around and a pleasant walk to museums and other attractions.. and train stations are just minutes walk in all directions too, so easy to get around the city from here. Would definitely stay again!
