Pros (+) We enjoyed our stay at La Querencia. Eduardo and Pico were very nice and helpful, and the house had a lot of character. The house was across from a small park, a block away from the metro, and walking distance from bars and restaurants - a perfect location. Breakfast was a good way to start the day as well.
Cons (-) Our room was fairly basic and the mattress a little hard - but it all made it feel like you were staying at someone's house (a good thing).
