This Airbnb was truly great for our one week stay in Madrid. It is close to the public transit and main streets. Because it is on the back side of the building (windows don't face the street), it is extremely quite and you don't hear the loud noise.
The bed and pillows are on the firmer side- which we personally liked (firm but soft).
Ruty's communication is great- he has reminders and clear explanations of how to check in/out.
It's an affordable and simple place if you are looking for somewhere to crash after exploring the city!
