Perfect apartment! We could not think of a better location: one minute to the royal palace, the opera and the metro station. There are many nice cafés, restaurants as well as shopping areas within walking distance. Nonetheless, it was absolutely quiet in the apartment and you do not hear anything from outside when the windows and the door are closed. It is located on the first floor and there is also an elevator. The apartment is super modern, fully equipped and perfectly clean. You can find many nice details which make you feel at home. The mattresses are rather hard and very comfortable. When the shutter is closed, it is 100% dark in the room. Therefore, we slept very relaxed and long. Two bedrooms are very small and one is big (and so are the corresponding bathrooms). But the whole apartment is very spacious. The meeting with the contact person was short and efficient; Ben was really nice and helpful. We totally recommend this apartment and will definitely stay there again during our next Madrid visit.
