Super impressed with the location. Very close to both Santa Domingo and plaza de españa line! Walking distance to all the attractions, Zara, Primark. I would definitely return if I come back to Madrid. They even did their best to allow my to check in before 3 and they kept to their timeline, 1pm. Very very impressed.
2 things though: Some people may have some difficulties if carrying too many luggages as there are flights of stairs you have to climb with your luggages from main gate to the lift or rooms. Depending on the level you're renting.
Another point is that the WiFi is so weak the network was very slow.
