Javier (the host) is very helpful and communicative. In the shared (with the host) living room and kitchen you will find anything you need (Javier provides even coffee, tea and etc.).
The room is not too big but has enough space for 2. It has a window to the small internal area of the building but not much light comes in. In the room, you have several different pillows, blankets. In the bathroom toiletries. Honestly, you get more stuff here than in many hotels :).
Location perfect - step away from metro station (which doesn't have an elevator if you are traveling with big luggage), local markets, shops, sightseeing places can be easily reached by foot. But the sound from the busy street doesn't reach the room that is just beside the host's room.
In general - a clean, comfortable place with easy electronic access and good wi-fi (if you need it ;))
