Great apartment with everything you need. It's in a quiet, non-touristy neighborhood, but within walking distance of many shops and restaurants. It's also very near the metro, which is really easy to use.
Rosa and Miguel are fantastic hosts. They picked us up from the airport, pointed out sights along the way, gave us a tour of the apartment and showed us how things work, and showed us on a map where to find sights that might interest us. They had also stocked the apartment with snacks, fruit, wine, and more! They checked in with us during our stay to make sure we were getting along all right, and took us back to the airport at the end of our stay.
I stayed for 6 nights with my husband, two teens and a tween. We would definitely return to this apartment. You can't go wrong with either this apartment or these hosts.
