Well-located apartment (in the center of Madrid). The owners were welcoming and available. However, the bed was too soft so my girlfriend's back and mine suffered quite a bit from it during the length of our stay. The shower is way too small. It is extremely difficult and painful to fetch the shower gel down below. Finally, the walls are so thin that during our first night I had the impression there was a rat when actually it was the neighbor's dog playing and scratching all night. Next time I'll aim for a more comfortable stay.
