Gabriela and Luis were great hosts, always very quick at responding to my questions. I haven't had the chance to get to know them well, but they were very nice.
The place is located in a residential area near Sagrada Familia - you can see local families playing in nearby parks and attending the church. It has all the perks of a residential area - it's quiet at night, safe, and has plenty of places for buying groceries, and so on. If you prefer this kind of environment, I highly recommend this place.
