This is a modern apartment in a residential part of the city. It's on the ground floor next to commercial units, as such it opens directly onto the street (which is very quiet).
There are two windows at each end of the apartment, but because of they are at ground level these windows are both frosted. So while there is some natural light, I felt a little detached from the outside world.
It felt to me like the apartment is very much run as a business. So on the plus side its modern and clean and well equipped. On the negative side there are no personal touches like coffee or filters to go in the coffee machine. There was also no chopping board and the only sponge for washing dishes was a dirty one under the sink (I just hope that was for the dishes!).
Communication was prompt, but felt automated. You are also left in no doubt what the financial penalties would be if you were to lock the keys in or stain the towels due to signs up in the lounge and kitchen.
It is a nice apartment however with good bathroom and comfy bed. I liked the non-tourist nature of the location and metro was very close. A good apartment to use as a base to explore Madrid.
if you do stay there then make a note of the lock box code before check out time so that you can leave the keys there. This information is only in the check in info which disappears from airbnb at checkbout time.
