Quite a distance from Ciampino train station, not as close as expected. I would have rather lived near Rome Termini. The way to the hotel was not really safe and took 20 mins walk. In some parts there was no pedestrian paths, or they are covered by cars parked there.
The room looked nice though, it was what a 3-star hotel shall look like. But the neighborhood was really dull without any necessities like restaurants and supermarkets. What you can have in the morning is only the 10 EUR breakfast at the hotel.
And the service provided by the staff was not what a hotel should provide, more like a hostel.
All in all, go somewhere else unless you have rented a car.
