The apt is in the center of Madrid and walkable to many landmarks. The interior was just like photos.
The host was waiting for us at the building, let us into the apt, took care of paperwork, showed us how to operate things inside, thermostat, induction range, etc. The check in took less than 10mins, smooth and efficient.
The apt is just above the restaurants and bars. I am a city person so I was okay with people loudly talking late at night, or cars and motorcycles noise at distance, but the trash pick up was something else, smashing of metal trash cans right at your ears. Bring your earplugs if you want to sleep at night. Or party all night and sleep late like many other tourists there. I could not do it because I was traveling with my two small kids, whose bedroom was away from the street and had no problem sleeping at night.
