Fantastic location. 4 stops from the airport and 1 stop from Atocha on the Cercanías train. 5 minute walk to 2 metro lines, 1/2 block from major bus lines. Luggage can be left with the reception if you arrive before check-in. Issues: some faucets were loose and there was some mold in a corner. Brought issues up with the host and said he would take care of it, so hopefully won’t be a problem for future guests.
