We stayed here for 3nights with family. Nuria was so nice and wonderful host and this apartment perfectly matched what we want. We checked in late and checked out early but she kept contact with us very well. It was big enought for 4 person(adults), cleaned, well decorated and equipped. It had a elevator, washing machine with washing powder, fully equipped kitchen.
The location was also perfect. Very central, had lots of hip bars and restaurants. There's a supermarket('Dia') right next to the apartment with good price. Recommendations book she gave us is also helpful. We visited 'La mucca' and it was so nice.
We really thanks to Nuria and we definitely comeback again if we had a plan go Madrid.
