Lovely apartment in a great location. Very close to Gran Via and Callao metro station. We were able to get a taxi for under €15 from the train station to the city centre. When we arrived in madrid we message renan and he was able to message almost immediately with the information we needed. Once at the apartment we just let him know and he sent someone to let us into the apartment.
Once there we were shown the apartment and everything was clean and accessible. Lots of towels available and welcomed with a nice bottle of Spanish wine, water, cokes and some beers.
Great hospitality, I would highly recommend his apartment to anyone in madrid for a few days.
