Great space, I wish I had booked my first few nights in Madrid here, b/c it is a hell of a deal.
Clean, centrally located, easy to get to the airport.
I had problems getting there at the time I originally said I could get there by and Fernando sent someone to meet me with a key at a later time, which was very helpful. I only stayed here one eve - it was a last stop before heading to the madrid airport of a multi city trip for me!
