The place is clean, it is in a "non-turistic" neighborhood with places to eat that are both good and cheap. There is a bus station very close from his house (less then 5 minutes) which goes to the center.
From the airport there is the bus 759 towards Restauradores which takes you there and the tickets can be bought inside the buss for 1.8 euros. We took the cab and it was a crappy experience.
Pedro is super friendly and speaks English very well. He lives upstairs. His recommendations are really good. He was so polite that he asked us if we mind if a friend of his will come and stay in the other free room while we were there. In the end we became friends. We totally recommend him.
The internet is reliable. We have been working remotely during our stay and we had no downtime.
