Me and three friends stayed in Ineke's house last weekend. Ineke couldn't he there but her friend Jean greeted us, she stayed a while to give us lots of useful information which was really nice.
The location is really good, it's a 10 minute walk to a free ferry which comes every ten minutes, this takes you right to Centraal Station, which is not only central but has direct trains to the airport (which take 15 minutes)
The house itself was lovely - two big bedrooms with comfy beds, two toilets and a great shower. The best part had to be the garden, a spacious garden with nice out door furniture, one of the bedrooms has a cool balcony which looks over it.
All in all I couldn't recommend the place enough. Friendly, clean, spacious and central. Couldn't ask for much more :).
