The apartment is in a fantastic location for exploring Madrid - there is a metro stop 2 minute walk away but we were able to go to all the major sites on foot.
The street the apartment is on has a couple of nice bars and restaurants which is great and we did not hear any noise from the street once in the apartment.
Check in was really easy with access codes to each door and it felt safe.
We did not spend much time in the apartment but the facilities were good.
We would recommend this apartment if you are looking to explore Madrid!
