The loft wasn't even close to what we we expected in advance (based on the photo's on Airbnb). The whole apartment was covered with stains (next to the bed, on the mattress, the couch in the kitchen and on the shower curtain).
Also the lighting next to the bed wasn't working. We did not even tried the appliances in the kitchen, no wonder if this also would not function at all.
In combination with the cigarette smell in the morning and the temperatures in the apartment (we stayed in June, there were only two old fans to reduce the high temperature) we did not had a pleasant stay at all.
Only advantage of this apartment is the central location (close to Plaza Mayor), if you're into the most touristic area of Madrid.
Clearly this apartment is being used as an ordinary rental, where the owner never spends time in this apartment. We would recommend no one of our friend to rent this apartment when staying in Madrid.
