The apartments looks like on the photos and Elvira gave us many options such as tea, coffee, cookies, hair dryer and even the iron. The apartments is placed very comfortably in case of visiting sights of Madrid (it is about 150 meters from Lavapies metro stations), but this place borders with some ghetto-streets (somewhere between La Latina and Lavapies metro stations, i don't remember exactly), that's why you should know where you better shouldn't walk after midnight :)
Description of the apartment is partly wrong. There is no WiFi router and internet at all. Also you should pay a deposit of 200 euro (this information also doesn't present in description of the apartments). This is important information, because we've been very surprised because we hadn't extra cash for pay this deposit, we are using VISA in most of cases (we are not EU citizens and using cash only for taxi).
Also we have some problems with boiler. It was very slow and hot water ran only first 10 minutes.
Summary:
It was okay.
