Have just returned from a three night stay at The Collector. I cannot speak too highly of our experience at this B&B, everything about it was "right" from our point of view - its location is perfect, right next to the major art museums and yet close enough to either walk into the centre of Amsterdam or to take the tram from just outside. The neighbourhood is quiet with plenty of places to dine close by.
Our host Erik, was very helpful with advice over where to eat, what to do and how to get there etc - having your own "Amsterdamer" giving local informed information as opposed to just tourist information made it seem that bit more special.
The breakfast arrangements being of a help yourself, when you want it basis again make for a very relaxed stay (even the eggs were from the chickens in the back garden!).
It is well equipped and spotlessly clean.
Would most definately choose again.
