The one thing this place has going for it is the location, you will hardly find a better location in Madrid, it is nicely furnished and well equipped even though the refrigerator and microwave are quite old and noisy - in a sense of “I had to turn off the fridge at night or I couldn’t sleep”.
BUT this place has no real windows whatsoever, the ones in the pictures are a bit misleading, they face a very small backyard and there is no daylight in the apartment whatsoever instead your room will be lit by the windows of your neighbors and the curtains don’t really do anything. Additionally, as it is facing that 2qm “yard” you will hear everything thats going on in the other apartments and I mean EVERYTHING, bring Orupax and a Sleeping mask!
it’s fine If you will only stay one or two nights and literally just need a central place to sleep but it is not a place to spend time in...
