We stayed for one night in Madrid. Three of us so it was cheaper than getting two hotel rooms for an overnight. Check in was at 2, which worked out great with our train arrival. The front desk is staffed much like a hotel, and they were great getting us checked in, orienting is to the area and also scheduling an early morning taxi to the airport for us. Since we left so early, they even packed us a generous picnic style breakfast to take with us to the airport. Wonderful service.
