Nice place!
The house is small but it has everything you need. Plus it is very very close to the metro stop "Ibiza" and just outside Retiro park (best place to relax and walk in the green). The hosts were very polite and answered all our questions, they gave us freedom to use the kitchen and to come home at any time we wanted. Definitely worth the price. In the end we were very happy and satisfied to have chosen this place to visit Madrid!!
