We really liked John's apartment, it was close to everything, shops, theaters, restaurants, La Gran Via and La Plaza Mayor among other important places. The advantage is that it is out of the congested area and the neighborhood is quiet, but walking a bit you can quickly reach the party areas. The apartment is very well decorated and has everything you need for a good stay. John is an excellent host and communicative. He allowed us to leave our bags before check-in time. Everything was very clean. I recommend John's apartment 100% when you visit Madrid!
