Max's apartment was well equipped for our temporary home in Madrid. Grocery store right across the street, fruit store down the block, surrounded by cafés and restaurants good for tapas, 3 minute walk from Parque de El Retiro, 5-7 minute walk from the Ibiza metro stop. If staying in the heat of the summer, be prepared to have window and fans going - or just go seek comfort in the city. You're in Madrid, after all!
Even though we never met face to face, Max was an excellent communicator. His friend Dino is a great co-host and just down the street should you need any help.
