This place is stylish and has everything you'd need. My friends and I stayed here for 2 weeks and we found ourselves at home. The beds are comfortable and there are enough pillows and towels for every guest. The apartment includes a washer, microwave, a small fridge (not a full on freezer), a TV, an iron and an ironing board. We made use of everything and it worked just fine! The building where the apartment is located is also very quiet. In the rare occasion you'd hear outside noise at night but it was not distracting at all.
The location is great too, it is not walking distance from the center of Madrid but it's very close to a metro station that takes you there. There are also several small cafes and restaurants in the area, as well as a supermarket for your daily needs.
