We loved our time in Madrid and the location of the apartment is incredible. But it is located in a very old building and has no sound isolation, you hear everything and it shakes when people walk above. It has the furniture from the pictures, and it is spacious and well equipped, but it's visibly old and seemingly used a lot. It didn't feel as cozy as it seems in the photos. It was not as clean as expected, there was hair and dust on the couch but it wasn't very bad and it was probably just overlooked. The advertised balconies are very small and the terrace on the roof is small, tilted and for us did not feel very safe.The host did reply quickly when there was some mix up with the keys but the guy that came to our door was speaking on the phone while interacting with us in Spanish (we don't speak it), so we didn't ask anything else. Also there is loud construction work across the building and it does not seem as it will be over soon. Overall, it was ok, that's all I can say!
