I reccommend it to everyone who plan to visit Madrid.

Localization is great - near royal palace and metro stations. still You don't have to move far as there are many restaurants, bars just around the corner - area is very lively - still room is quiet at night.

If You don't decide to move You can just chill in the apartament - with open balcony windows it is a nice place to rest even during a day.
It is perfect for couples. If You're more than 2 people someone would need to sleep on the couch (which wasn't a problem for me).

Wifi works perfectly. Room was clean. Hosts were very helpful. If I visit Madrid again I would definately choose this place again!
