Nice cozy apartment in central Madrid. All the major places can be reached on foot, you don't necessarily need to buy the metro tourist ticket. A big 24/7 Carrefour supermarket is just across the street. The hosts were reactive and offered us a free earlier check-in without us asking for it. The Nespresso coffee machine is superb. We found three small roaches in the bathroom during our one-week stay. The place could also have been a little cleaner, but a vacuum-cleaner was available, so we cleaned ourselves. The water boiler has limited capacity, so two people can't take a warm shower after another (we learned this the hard way) and it takes very long for there to be warm water again (45+ minutes). The lock does not pose problems once you learned how to operate it. I have a very fragile sleep, but I was not disturbed by the noise from the street. The Airbnb guests in the other side of the apartment can indeed be heard, but were mindful in our case. Overall a very decent stay.
