I stayed here for about a week, and it was an amazing experience for my first trip to Spain. Everything was as described, the place looked great, and the location was phenomenal (3-5 minute walk from Nueva Numancia Metro). I felt very safe here. I had one issue checking in when I first arrived due to a mistake on the part of the previous guest, and the host responded immediately and worked quickly to resolve it.
My only problem with this place was that it could have been a little bit cleaner. There was dirt all over the floor like it hadn’t been swept for a little while. Still, there was a broom and dustpan provided, so it wasn’t difficult to take care of it myself. I would DEFINITELY stay here again, and highly recommend to anyone looking for a nice place in Madrid.
