The flat looks like student digs at best, or maybe camping. No luxury at all, decorated as cheaply as possible, all the furniture is scuffed or stained. There is only one room which has 2 sofas, the washing machine, the kitchen sink and the TV in it. The bedroom is equally small. There is nothing in it apart from the bed and the overhead light fixture. The bathroom has no windows in it. The flat was cold and had no heating. We slept in our sweaters. The only good thing about it was the location. It is right next to the St Miguel market.
If I come back to Madrid (which by the way, is a phenominal city) I would definitely NOT stay here.
