Location is perfect, Malasaña is full of local shops right next to the flat there is a empanadas place which we indulge every day.
The flat is perfectly clean and tight, highly recommended!
The flat is good for 3 people, but still is a bit crowded with 3, the sofa bed is certainly hard to sleep on after the second night, other thing is that is missing a coffee machine, which for me is essential at any place, both easy fix.
