This place is basically run like a hotel. They have a receptionist so check in was very easy. They provided additional towels, coffee pods, laundry pods, etc as we needed them. The space is huge and there was plenty of room for the 4 of us. There are limited paper products in the kitchen so plan to buy some at the local supermarket. You can walk to the palace and then to lots of shopping and Plaza Mayor. We didn't use the metro in Madrid, but used the MyTaxi app to get around. Would definitely recommend this place!
