The apartment is really nice, beautiful, clean and quiet, and the location wonderful, it's easy to go everywhere by foot or to take the metro, which is just a few steps away. The nearest metro station has a direct connection to the Atocha train station, and also the bus stop for the airport bus is at a walking distance.

Everything went smoothly and the hosts are very friendly, but we did have a few minor obstacles. One night we got stuck in the stairs for 1,5h because the hallway door wouldn't open. But apparently they are going to change the door. And the next day the neighbor asked us to leave the door open for the telephone company as we were leaving (and also advised us to take our passports with us.. Also he felt the need to mention how he "hadn't had any sleep" the previous night because the host had to wake him up to open the hallway door).

But as said, all in all, the apartment is great, and I'd definitely stay there again anytime!
