This is an artsy, slightly quirky space, that somebody very likely actually inhabits while not rented out on airbnb. We liked the fact that it had 2 bathrooms, and generally its generous size. Also, we liked the feeling of actual home, rather than one of those minimalist 'only for airbnb' apartments that you often find. The master bathroom is very close to the bedroom, think en-suite, and it is nicely done. Check-in was quick and uncomplicated, and communication was very good throughout. Internet is fast. Location is great, and you can walk to everything in downtown Madrid that is likely to interest you. For a nice dinner 3 mins away from the apartment, try Juana La Loca
The bedroom window only goes out to an interior court (upside: very quiet), and the shower in the small bathroom felt somewhat minimalist in size. We felt the place had less light, and more transparency towards the neighbor across the street than in the pictures. The half-eaten onions in the fridge we just ignored
Overall a good apartment, if your budget allows it
