We stayed in one of the beautiful flats/apartments at the Amsterdam Farm Lodge, a farm-community of small businesses (the lodge, a pancake restaurant, brewery, vegetarian restaurant, children's nursery, beekeepers, etc) during a recent visit to Amsterdam.
Everything was amazingly clean, well taken care of by Rogier and Nicole. He welcomed us with a smile, had baby cots/cribs ready, and some suggestions about nearby things.
It's a little bit off the beaten track, in Amsterdam North, but was great for the kids to come back to in the evening. A quiet, peaceful space. There are plenty of gardens to explore, bikes and scooters that the kids rode around on, etc. A quick bike or bus ride down to the NDSM pier gets you on a free 5 minute ferry ride that deposits you right at the Central Station.
