Jero is a good host. He's communicates with you before you arrive, and gives great directions to the apartment. His nephew met me at the apartment to let me in and show me around.

The apartment is exactly as pictured. It's a studio apartment with a very small, but fully functional kitchen (including a stack washer/dryer), and decent sized bathroom. For a small space, the apartment has a good amount of drawer and hanging space for clothes. The apartment could not be more centrally located. The Gran Via Metro station is 20-30m from the apartment. While the apartment is in the center of Madrid, it's internal location in the building makes it very quiet. You will hear the neighbors coming and going because you share an entry with them, but you never hear them in their apartment. I never heard any sounds from neighbors. The building is quiet.

The apartment is completely empty when you arrive. Unlike other Airbnb apartments I stayed in this summer, there was no coffee/tea, welcome bottle of water, soda or beer. There were no toiletries in the bathroom or dish towels in the kitchen (which meant I had to use a lot of paper towels). There are no tourist info packets, metro maps, museum info, or anything to help guide you around Madrid. That's all fine, just know once you arrive if you need anything (like coffee/tea or water), you'll have to go get it. Fortunately, two doors down the street is a small market where you can get some items.

The a/c's fan in the apartment is set very, very low. It's nice and quiet, but doesn't really move the air much in the apartment. The temperature in the apartment was ok, but it was a little stuffy. The kitchen and bath don't benefit much from the a/c, it's felt in the lounge area most.

With a more powerful a/c unit or a fan to move the air, I'd stay here again. Jero is a friendly, communicative, helpful host, the apartment is a nice unit, and its location is ideal.
