Great apartment in a central location (next to Plaza Mayor and Sol station)! It is also across from the famed Chocolateria San Gines. Apartment is in a great old building with plenty of European charm but the inside has been completely updated so you get the best of both worlds. Only caveat is if you're a light sleeper to bring some ear plugs - the two rooms in the front facing the street can be quite noisy up to 2 - 3 AM. Otherwise, plenty of room for a big group. Ramon even left us some traditional New Years snack when we arrived to celebrate the New Years. Highly recommended to stay if you have a big group and want to stay central in Madrid. Almost everything we did was within a 30 min walk so it was great!
