We were suspicious at the low price, but were more than delighted by the appartment. Especially the location is great, literally dozens of Restaurants and Bars in all kind of styles within 3min by foot. Close metro station, very un-complicated host. If you want to stay for a longer trip in Madrid, it might be a bit small, but for our case (3 nights) it was easily large enough, especially for that price! We didn't use the Kitchen/appliances, but shower/toilet were fine, so I would expect them to be good as well.
