The flat was clean and well-located (close to the Arguëlles metro), in an enjoyable neighbourhood with shops and restaurants/pubs close by. Despite the 40-degree heatwave outside during my stay, the temperature inside the flat, which is a basement flat, was OK. Since it is a basement flat, you might be more exposed to some street noise/sounds (footsteps, cars,...). I used one ear plug, though, and slept well. One minus is that the bathroom door could not close (a carpentry issue), but since I was there on my own, that was not really a problem. The flat is well-equipped and modern, with minimal decoration.
