Host Javier is highly communicative person that answered every question quick and transparetly. He made effort to be able to accomodate us after late flight and was helpfull before and after that. Place is located perfectly, few steps to metro or 24h big supermarket, next to every place you want to visit in Madrit. Unfortunetaly we were at location in hotter than usual August so it was very bad place to live most of the time because of no climatization and also very weak air ventilation in flat, even in the nights.
The most basic things for long stays are inside but many things are old and broken, like broken shutters and broken hangers for sunshade, refrigerrator not closing well and without light inside, lamp with broken clips, a little burned iron, only one old and also burned pan etc. Ice cubes forms was so old that it get broken in first week so we needed to buy new ones as it was needed for mobile ventilation machine. There is no vacuum cleaner so place is hard to keep clean.
I would reccomend this place for stays to not more than 2 people (its seems to be larger on photos, but in reality 3 people there is too much considering 2nd floor has the weakest air ventilation) and not in hot months. In summer price for that flat seems to be not exal to quality because its conditions made it really hard to stand heats. I believe it could be really good place to live after some innovations.
