I have now stayed at three different places all within 2 blocks of each other. Comparing the three, the cottage is slightly more expensive and the smallest. It is also the nicest in terms of decor, comfort and being well-stocked. It is the only place of the three with air conditioning.
Instructions and communication were clear and timely.
The location is a touch further from the beach (still only a short walk). Being on the canals and having access to the kayak/boat were big pluses and more than made up for the extra minute walk to the beach.
The available bikes were old and creaky. One of the locks was very difficult to open.
Overall, as a couple with 2 children, it felt cramped. A couple with one child would be OK, while the cottage is best suited for 2 people. I would stay again if I could not find a slightly bigger place in the same price range. For fewer guests, I highly recommend the cottage.
