We spent 2 nights at Edu’s place, which is good choice for a short visit in Madrid.
On one hand, we loved the location of the flat, we were close to everything. The room was clean and we were happy to find it cold and air conditioning on after the long journey and day.
On the other hand, the room looked a little bit different from the pictures, there was an OSB behind the bed which was not on the pics and the timbers on the ceiling neither. We didn’t know it’s the 4th floor, walls were thin and not enough space to put your stuff, ents are falling to the bed from the timbers. Our first impression was very bad because the expectations were higher, but all in all I would recommend it for a short visit. Price was reasonable, so 4 out of 5
