Schiphol is a major hub, so if you need a good night's rest, this is a good place. If your luggage is heavy, you may consider leaving it at luggage deposit in Schiphol (EUR 7 for 24 hours) as the stairs to the rooms are pretty steep! Connections to the airport are regular and free. The restaurant and adjacent pizzeria seem to be good, but the prices are steep! Think in terms of EUR 15 for a pizza. You're better off eating from one of the eateries at Schiphol Plaza.
If your booking includes breakfast, well and good. It offers a good selection by Dutch standards, and you also get sausages, bacon and scrambled eggs. But if it's not included in the price, have breakfast at the airport. At over EUR 14 per person, it's definitely not for those on a budget.
The rooms were good and clean. Bathroom was spacious with a good bath. No airplane noise at all.
