The garden house is equipped with everything you need, e.g. a real bed with a good mattress that's big enough for two tall guys, a cozy open living/kitchen/dining room, toilet and shower room. Yes, it's small, but big enough to feel comfortable as a couple. It is so conveniently close to the city yet absolutely private and far from being expensive.
I think it's a special, unique way to spend some days in Amsterdam. Thanks Reinhart!
