The ONLY* good thing I can highlight from this place is the location, Malasaña (which is superb). This studio has been poorly maintained (no attention to detail). The bathroom is probably the BIGGEST* drawback; it has heavy mold all over the floor tiles and the window inside the shower, also the drain hole gets flooded.
The other pain point I had was that you have to pick up the keys to check in from a Fruit store a couple of blocks away; not a big thing, but if it is raining in Madrid (which happens), this can turn in an inconvenient. I’m sorry for the owner, but I can’t recommend this place. It needs a lot of love and work.
