We had an awesome stay at Sergio's. The room and bathroom were both really spacious, clean, and neat as described. We had a really late check in due to flight delay, however, Sergio still waited for us and spent the time explaining to us how to use the metros and which attractions and restaurants we should try. On top of it, he helped us call a taxi when we had to leave really early on our check out day. He was the best host we have ever experienced. Thank you for everything!
