Excellent location, located close to the city centre (accessible by walking), some of the top-rated restaurants, bus stop and metro. The apartment was clean and tidy, kitchen well-equipped and instructions were clear. If there was anything to nitpick, it'd be the noise and loud stomping generated by surrounding guests, occasional smokers at the ground floor, and that the internet-based door lock did not work at times. But overall, it was a pleasant and extremely worthwhile stay. Marco and team were communicative and responsive to our requests. Will recommend this place to those visiting Madrid.
