Noelia is an incredible host. She was flexible and met us when we made it to Plaza Mayor and showed us everything we needed to know about the apartment, including a guide of the surrounding area. The apartment was incredibly comfortable and was the quietest place we've stayed in our ~2 weeks in Europe. The air conditioning was amazing and extremely efficient - we found we only needed it on for 20 minutes or so to cool down the apartment in the hot afternoons. We cooked breakfasts in the apartment and found everything we needed. We also did a load of laundry and were equipped with everything for that. Overall, this is a very comfortable and functional apartment. The only surprise of our time in Madrid was more of Plaza Mayor than anything else. There were quite a few homeless people that set up box shelters around the perimeter of the square at night. If this turns you off and you plan on being out late or getting up early, then maybe think about a different area. This didn't bother us much though, as the building is safe, with a door person and a secured building door.
