This apartment was perfectly located (few minutes walk to all Madrid Center attractions) and the check-in process was super easy. The building/apartment looks like a brand new construction with controlled access and security cameras in most areas. Fully stocked kitchen (appliances and dinnerware) and laundry room were a plus. Something to highlight was the excellent noise insulation of the windows, this was a cause of concern for me since the building is located in a busy area, but I can attest that once windows were closed, all street noise was gone. If you are looking for a very well located spot with excellent amenities and safety, I definitely recommend this building.
