We booked this room as it seemed amazing from the pictures, because of the mostly positive feedbacks it had, for the kitchen, for the position and because of the self check-in, as we arrived late in the evening.
At out arrival, the room was dirty (with other people's hair on the floor)and there was a terrible smell from the bathroom. The pictures are very well done and make the room look much better than it is in reality (congrats to the photographer!). The kitchen it was full of dirty dishes (left from other guests), so we couldn't use it. The walls are thin, so you can hear everything from other rooms untill late night.
The only plus it has, it's the position, 10 mins walking from Puerta del Sol and close to metro stations.
