Nice place, a little bit tinier than I expected but with the 2 bathrooms was very good for 5 people's 2-nights stay.
Wifi worked well, we found all the amenities we needed and the location was very central.
One very bad note for us was the communications: we informed the host that we would have had a late checkin, but we didn't receive clear information on how to enter the house until the very last moment (once arrived in Madrid). The app they gave us for the registration said that we would have had a code to access the house at 3PM the day of our arrival, then changed it to 23:59PM (!!), we where afraid of not being able to get in and we did not receive answer for a long time. Moreover we had some troubles with the registration via app, pay attention on how it works. It may not accept italian older ID, nor driving licences.
