This apartment is lovely, it's located in the very heart of Madrid at only a few steps from the Plaza Mayor. Check-in was easy and quick. The apartment is brand new, clean and gorgeous. It surprised us how soundproof it is to outside noise - even though you're on one of the busiest streets in Madrid, you can hardly hear anything. There was some noise from inside though, when someone else took a shower or the apartment next to ours was being cleaned it was quite noisy. Other than that our stay was lovely.
