I've been stayed several times in Amsterdam ( six at least), and this is the best hotel I ever stayed!) .
We were in the "Rembrandt Suite", an amazing and very big room, furnished in antique style, with following amenities:
gas fireplace (very nice and better than watching a tv!), comfortable sofa, a writing desk, lcd tv 42'' , nespresso coffee machine with capsules, a dock station to connect your IPod and listen your music, a nice luxury bathroom (in amsterdam it is very rare) with a hot tub, a lot of towels and wellness products.
An hearty breakfast in the room, and friendliness of the staff complete a dream holiday in this fabulous hotel !
I highly recommend it to everyone!
