Diana was an amazing host & very accommodating ! Upon our arrival she met us at the airport and provided us with all the information needed. The apartment itself was great & everything you will need for a few nights in Madrid. The staircase going to the 4th floor will be a test of your endurance, pack light (we did not...)! The apartment itself is very safe, multiple locks to even enter. Be careful with the low ceiling in the entrance hallway to save yourself a sore head. The apartment is a reasonable walk to all major sights and in a very hip part of town. Enjoy !
