Very clean, quite, and convenient, taking the train C1 direct from the airport, walking to the near train and Metro station Princip Pio about 5 min, walking to Royal Palace or Plaza de Esp about 10 min, three grocery stores and at least two restaurants down street. The check-in instruction is step by step detail and clear and responding comm being very efficient and accurate in time and checking out procedure is even more simple. Because of nice host, apartment location, and convenience, strongly considering rent back if chance and recommend to friends.
