I had a perfectly nice stay with Fabiana on a last-minute overnight layover close to the Madrid airport. She and her daughter were very welcoming. The bed was comfortable, the room very clean, and they even made me a simple breakfast the following morning, which was very sweet. It's a little easier to get to the apartment from Terminal 1 than it is from Terminal 4, but with the free airport shuttle between terminals and a short hop on a local bus, it worked out. All in all, a nice overnight stay.
