As said in the description, there is a really BIG construction going on in this old building, so you will practically live on a construction site. Furthermore there is almost no daylight in this appartment such that you will have to turn on the lights even if outside it is super sunny. The bathroom is very narrow and we all have strongly hit against the heater which is mounted in a very bad place. The shower has mould so that none of us wanted to use it without slippers and in general the cleaning was not done very well such there was a lot of dust on the floor. However the location of the appartment is very good and the arrival was working very well. The appartment is close to many nice attractions in Madrid such that if you really just want a place to sleep (until 8 am when the construction work starts), then this place is fine.
