The apartment was well positioned in the fascinating (and safe) Barranco district. The hosts were very helpful, responsive and speak excellent English - although note that the room is actually a room in a building of apartments which includes private residences, so the hosts are not actually on site. The building security officers are friendly and professional and while they do not speak English, they were able to help us with check in, check out and ordering a taxi. The hosts were able to stow our luggage for us when we arrived several hours before check in, which was a big help.
The apartment was very clean, well furnished, nicely decorated, and with a full kitchen.
The only negative was that the windows are not double glazed and the traffic is quite noisy from the street (used ear plugs). Otherwise, a fantastic hotel at a good price.
