Michael was very communicative and helpful. The place is very clean and as described. It is on the 4th floor in a building with an elevator, but you need to walk about 12 steps up before you can get to the elevator. The combo washer/dryer is awesome as well since we are light packers.
The location is fantastic. There is a Metro stop in front of the building and a taxi stand across the street, which makes it very convenient to get around a big city like Madrid. There is a small grocery store about 25ft out the front door, which you can get fresh o.j. in the morning and cafes and restaurants steps away.
The only thing to note is that there is a loose manhole outside on the street and every time a car drives over it, you can hear it rattle. So you can't sleep with the windows open. But the apartment is still great!
