Nice apartment in a non touristy, generally quiet area of Madrid that is walkable to many restaurants and shops. One plus is that there is both a washer and dryer here (although we did not use it, dryers are rare in Spain).
The host was very responsive and friendly, but there was some confusion as we were being messaged by two different people at one point, and had to ask for check in instructions as they were not shared proactively.
This would be an ideal place for a family as you need to climb a tall ladder for sleeping in the twin beds, which were comfortable.
Note that there is only one door to the apartment, and it opens directly onto the street.
