This is an incredibly special place to stay -- you're up on the top floor of an old Amsterdam building, incredibly centrally located, and it's spacious and inviting. If you are able to climb stairs easily, don't miss the chance to stay here!
This place is probably best for a couple, as there is a large bedroom on the same level as the living area and kitchen. The two twins are up in a loft area that requires using a pull-down attic ladder -- not good for small children or if you have large teens or other adults. Gerrit does provide fans, so it was comfortable to sleep up in the attic/loft.)
We loved our stay here!
