Daniel's apartment is in a great location and as pictured. It is very clean and updated. Communication was a bit spotty, but most of the time he was quick to respond.
We would definitely recommend the apartment if you do you have a lot of luggage or do not have mobility issues.
NOTE: The listing stated there is an elevator. This is partially true as there is an elevator in the "building". But to get to the apartment, you have to walk up multiple flights of stairs from street level to it (which is located on the first floor). The elevator starts on the first floor, which is moot since the apartment is on the first floor.
The listing stated: You will have access by stairs to the elevator from which you can access the apartment. I read this to mean a few steps in the "lobby" floor and then take the elevator to the apartment.
Madrid was the 2nd to the last stop on a 3 week vacation. Each person had a luggage and carry on. It was a lot of work to bring the luggage up and down the stairs.
