This was a wonderful flat! It looks just like in the pictures, beautifully decorated, modern kitchenette, a lovely, stylish bathroom with a spa shower and generally good space for a studio. The only thing that was negative is that the flat doesn't have good sound insulation like many other flats in Madrid, so you could hear everything from the street and the bar below as if it was inside the flat (which is not fun at 4am). So if you are a light sleeper like me, bring earplugs. There was some problems with the hallway door getting jammed, so I had to let some neighbors in at one point (who were very nice).

Otherwise the location is amazing, Melvin was a great host who helped us get a taxi to the airport for an early flight home and gave us recomendations for good places to visit in Malasaña. I highly recommend this flat, and we will hopefully be using it again on our next trip to Madrid.
