First off, welcome to FT,
caseyn1. It speaks well for anyone whose first post is a helpful and information-sharing one, such as yours.
I'd agree that it's better to stay within the city center, and that the bookings.nl site is a good one for hotels. I have also had good luck with
www.hrs.com . Using Priceline has its advantages and drawbacks; more info at the notorious BiddingforTravel or BetterBidding sites.
As for location, I prefer the Leideseplein area, especially in warmer-weather months because of the proximity of the pleasant Vondelpark. My second choice would be in the Dam-Munt areas, but definitely not the station area.
