Although we didn't met Mauricio in person, the communication was good.
The apartmant was clean an well equipped with everything you need, the wifi and the tv worked fine.
The neighbors were a little bit noisy but nothing intolerable.
From the apartment you could reach the train station in 10 minutes with the bus 17, and from there the city center is 5 minutes by foot.
Generally we enjoyed our stay, the city was absolutely amazing.
