Kelli and Henk's apartment was the absolute perfect base for our stay in Amsterdam, I would absolutely recommend it to anyone. It's spacious (except the bathroom!), full of life, comfortable, a real joy to come home to. We loved sitting on the roof terrace morning or evening, listening to their extensive playlists, and one tired night we even watched a movie on the very comfy couches. There was a basket of food and information left which takes the stress out of the first morning. There was a supermarket and bike rental very close, we rented bikes and loved the ride through Vondelpark into the city each day. We bumped into the neighbour a couple of times too- she was lovely.
I'd recommend you ask in advance how to use the oven as we couldn't figure it out and had to message Henk. Also note that in the downstairs sleeping area (if there are 3-4 of you) there's no blinds so you may be woken by the sun.
Other than this, there was helpful notes everywhere and Kelli and Henk were both very quick to reply, so even if you do have problems they're great hosts. We were both so sad to leave this oasis, and such a great city, it could only have been better if Malcolm the dachshund came as part of the package!
Thank you for having us in your wonderful home, Kelli and Henk.
