I stayed at this place for 3 days during my trip to Spain with my friends.
We liked our stay at this place. It is located somewhere in between main train station and down town. That was a big plus, as we simply walked from main station. The kitchen was well equipped.
On the other hand, it is a little bit smaller for 5 persons and once you open the Sofa bed, you can not go to kitchen. Also, we were not able to find Wifi password throughout our stay.
