The location is absolutely ideal for anyone coming to Madrid. You are in the middle of everything and can walk to all of the main points, and you're also close to a couple of Metro stations. The apartment is as described, and was a perfect refuge for us and our dog to rest. Of note, while there was not too much natural light since the apartment is on the ground floor of the building, the soundproofing was quite good and you were able to forget that there was a huge city outside the building. Jon was a great host, and made sure that we had a nice welcoming detail waiting at the apartment after a long trip, which we immensely appreciated!
