My family (3 of us, including 2y old kid) stayed at the apartment for 60 days.
Natalia and Enrique were excellent hosts: friendly, talkative, responsive, accurate.
Both apartment and location worked for us:
terrace is huge with a great view, and only 5 times during our stay we did not start our day on it
very quiet (can't hear regular traffic) if inside
accessible via public transport (several lines)
several big grocery stores in the walking distance (<500m)
big park nearby
taxi station just across the building
our kid was running on the terrace all the time
rooms: sun wakes you up, moon greets you at night
We do recommend it without hesitation.
