If you want a nice hotel with big, modern and clean rooms not that expensive compared to small hotels located right in the center of Amsterdam I totally recommend it; we just had an issue during the check-in: they didn't find one of the reservations that was already paid! fortunately I printed it at home so the receptionist took it and disappeard for about 10 minutes, when she finally returned said that they "had found it", but I think they just had available rooms so they gave us one. The people that were with another receptionist next to us had the same issue, so it maybe a systematic problem they need to pay attention to. Recommendation: take a printed copy of your reservation with you.
The breakfast has a lot of variety but is on the pricy side for an average tourist.
