This is a nice, useful space if you mainly plain to be out and about in Madrid. It is a basement apartment, so no direct light gets in at all, and most of the windows look out on walls and don't open. Our communication with our host resulted in some confusion - we arrived early and were told we could check in at 1pm, but no one was present for a while, and when we did finally get into the place, the previous occupants and their family members and their luggage were all still in the place. I think the hosts weren't aware of this, so no problem. We dropped our luggage and vacated, so the place could be cleaned. It is in a great location in Madrid - right near the Atocha train station and the enormous Retiro park.
