This flat is incredibly good! I went to Madrid for business purposes and my colleagues and I were the first guests to use this flat, so all equipment was brand new. Location is also excellent. The place was impecably clean. I found cumbersome to the need to communicate with the guest through a 3rd party platform but all went fine in the end. Also, there's noise from the outside coming inside the flat but nonetheless I managed to sleep well - the bed is very comfortable. In an overall, I highly recommend this place!
