Juan Carlo's apartment is in a very central location, easy access to a very interesting part of Madrid with lots of shops, eateries and a market within just a few steps. The place is very clean. There may be several other guests there but my stay was quite quiet. The kitchen is available, and the bathroom is large and very clean. He has a small dog, quite cute and not at all noisy or in the way. Juan Carlos runs his airbnb very professionally.
