Four of us stayed in Josefina's apartment for a week while we were in Madrid. It was everything we were looking for and more. Super convenient to get to the major tourist sites, clean and had everything we needed.
It was right in the heart of a great area for bars/restaurants (La Latina) and yet very quiet in the evening as well.
We had a rental car which we parked at a nearby parking garage, which worked out really well. We were able to pull the car right up to the front door for loading/unloading which was super convenient.
