I have had only good experiences with Sheraton hotels in airports, and this was another one.
I had arrived from a 24 hour connecting flight so I was a bit tired and jet lagged.
I got there very early, and I had booked my room from the night before. Check in took less then 5 minutes. Very professional staff.
The hotel is super conveniently located on the airport terminal. It is modern, rooms are very comfortable, staff around the hotel is very professional and helpful, room service was very good. Internet was very fast, there are 24 hour a day tea/coffee facilities close to the lifts on the floors ( good quality, excellent presentation ).
The health club is a bit small, but it is ok for a workout. I had a great time there!
On the terminal, which is less then a 5 minute walk you can find everything you need, from food, electronics, exchange, and it is very easy to get into Amsterdam. It took around 20 minutes or so by train from the airport terminal.
