The check-in went very smoothly. Mercedes (Jose's sister) was very helpful at showing us around the flat, recommending places to visit. Also ordered us a taxi in advance for our very early departure. It was very nice to find a welcome drink (a bottle of cava) left for us :)

The flat's location is perfect if you want to visit the museums and other major landmarks in Madrid. Besides that, all the best restaurants of Madrid are just around the corner!!!

Highly recommended.
