Loved my stay on the houseboat! Felt like I was truly living in Amsterdam during my time there.
The boat is like a floating studio apartment and feels quite spacious. If you're taller than 5'9'', you may have to duck a bit in the living room area.
Bed is super comfortable and you can people watch the activity on the canals out of your porthole, which is a very unique and lovely experience.
The bathroom is a combination shower/toilet with a little sink. Works great for a single person, especially if you give the area some time to dry after a rinse.
Location is incredible. You're four minutes walk from the red light district, but the canal the boat is on is quiet, scenic, and residential. I found it very convenient. There's a bike rental place a bridge away and a huge Albert Heijn supermarket about 5 minutes away.
The washer/dryer wasn't working during my stay, but the hosts graciously offered to wash my items next door.
You do have some neighbors on an adjacent boat and the boat you're staying on is split into two completely separate residencies, with one half being owner occupied. As a guest, you have your own entrance. There's no noise transference, but the neighboring boat residents will occasionally walk across the top, so you may see/hear footsteps. It didn't detract from my sense of privacy at all and very much felt like my space throughout.
I would absolutely stay again! Thank you, Cees!
