Staying with Raul was truly a pleasure. We got a lot more than what we were hoping for in terms of space and accommodation, and were astonished by the amount of care Raul had at the check in. He explained us not only the normal house things, breakfast arrangements, the A/C unit and fan workouts..., but also how to get in and out to central Madrid (an urban train "cercanias"), the best way to get to and from the airport, the schedules of metro and bus if necessary (which it wasn't). All of this in a book, with handy maps and plans. Raul explained the main attractions in Madrid, and how to get to them.
The house is 2 stations away from the main station and is easy to move around. The apartment is spacious, very clean, with the possibility of eggs for breakfast, and to use a kitchen for who ever wants it. Loads of other details that made our stay in Madrid, very pleasant.
