Our stay at Rosa's place was excellent. I have no complaints whatsoever. The location is very centralized - within a 15 minute walk from most sights, though not close to any metro stations. There is air conditioning in both the bedroom and the kitchen area. There is even a washing machine and a drying rack. Small warning -- if you bring heavy luggage, there is a short flight of stairs to cover before you reach the elevator.

Before the trip I messaged back and forth with Rosa; when we got there we primarily interacted with a woman named Paola. Rosa helped with booking a taxi from the airport, and was up front about all the fees and costs in having a late check-in. Paola met us there, and later was available for us by text to troubleshoot a wifi issue. I found both to be very friendly and helpful.
