José is a great guy and his apartment is nice and clean. It have access to public transport, 10 min walking from the atocha railway station. If you go to Madrid by plane there is a express bus every 15 min from the airport to atocha and the fee is 5€.
José helped me with lots of tips about Madrid and also gave me a map and marked all the places I should see, where to eat, where to get discounts from.
I strongly recommend him as a host.
