i reserved by hoteis.com, going to Amsterdam with my wife and 2 children... 4 large bags, hand bags, etc... Good localization if you want to stay near the central station, but terrible acomodations... NO ELEVATOR, very narrow stairs, NO HELP with lugage, NO HELP with internet ( not functioning ), VERY EFFECTIVE TO ORDER CHECK OUT, no curtains at the bathroom, so be prepared to get very wet floor over the bathroom and bedroom, NO RECEPTION, just 3 sqmeters. Search for best quality paying just a few more...
In Brazil ou States you wold have a really 4 star hotel for the same price...
