We had a great trip in Amsterdam and we really enjoyed staying at hamed's place!
Hamed is a fantastic host, he's very nice and helpful. The room is very clean,nice and well furnished: there is a kitchenette (with a sink, a kettle, a toaster and a fridge) so we had tea/breakfast in the room and we prepared snacks for our long walks in the city. Beds are confortable.
The only disadvantage is the noise : because of the traditional windows, we hear noises from the street...so don't forget your earplugs :)
