We really enjoyed staying in Ana’s apartment. Because we were going to arrive late at night at the Madrid airport, we were given clear instructions of where we could pick up our keys. We took the express bus to the city and walked in 15 minutes to the apartment which we found with no difficulty. 4th floor but WITH an elevator which we totally were grateful for! The apartment was clean and with a lot of light. And very very quiet! It was easy to forget the busy night life in the streets below. The apartment is also strategically located to all the main sights. We never needed to take a bus. We needed to leave the apartment a little later and the owner was very accommodating. We really enjoyed our 5 nights in Madrid.
