Mercedes is a lovely host! She is very kind, polite and heartwarming person! She replies really quick and is there to help you, as well as her daughter, Ariana :)
The room is nice with a cute table in front of 2 big windows looking at a city view. The neighbourhood was very nice, a bit far from the center but full of markets, and the metro is next to the house!
I totally recommend Mercedes and her place :)
