I stayed here for about a month.
The apartment is very nice, one of my favourite AirBNBs so far!
It is next to a metro location in a very nice area that isn't too loud at night. The King bed is very comfortable and you can control the entire apartment; lights, shades, doors and temperature, from an App.
It has everything you need and the cleaning service is a great additional benefit.
The owner is also very quick to reply and very helpful. There are lots of restaurants and supermarkets close by.
I would definitely recommend this apartment for a short or longterm stay in Madrid.
