Roque's place was comfortable, modern, and perfectly located between walking distance to plaza mayor (and the royal palace) and plenty of great tapas bars/restaurants in walking distance of his apartment. The apartment had all the standard amenities plus additional amenities like excellent AC system, fiber optic high speed internet, and an elevator in the apartment which is a big help if you're on the last leg of a two week vacation and have accumulated a lot of bags. This isn't often listed in reviews but should be: the be was the advertised size and very comfy.
More than anything, the best part of the stay was Roque's excellent hosting. He communicated with us clearly where the apartment was located, worked with us doing a late check-in and even asked if we were hungry and if we'd like some suggestions of local restaurants we'd enjoy. Roque took his time showing us on a map where we were in the city and how to get around. Needless to say he made us feel very welcomed and helped us get around easily. Additional little touches that make Roque's place so special were a Nespresso machine with several different flavors, bottled water and milk in the fridge for us to use, and a nice bottle of wine he had selected for us.
I couldn't recommend Roque further. I would absolutely stay with him again next time I as in Madrid.
