Great stay in Madrid. The host was very friendly and gave us a detailed information when we arrived . We arrived there at midnight (1am) but he was still very kind and nice to us.
The apartment was clean and only shared with another room.
The kitchen well equipped with most equipments and cooking stuff.
The bedroom was big enough for 2 people ( bedroom 1) . The only thing to be concerned is a bit noisy during the train working period.
