David's apartment is ideal to visit Madrid, location, cleanliness, contact with the host, all was perfect.
The room is nice and quiet, you have your own bathroom which is great, access to a very nice and tidy kitchen. Even a shelf in the fridge is dedicated to you.
The area is one of the most trendy one in Madrid, so no problem to find good places to eat or entertain yourself.
I highly recommend David's place.
