We had a very pleasant stay at Casper's and he is a very good host. It's a relaxed, very quiet and cosy period apartment. Plenty of space and room to breath with large window water views. There are the customary stairs, typical of period houses in Holland. It would suit large groups very well. All amenities were as listed wifi etc and clean. We walked everywhere from the island which for us was fine. If you have your own transport or bikes then this would be an excellent stay if walking was not your thing. There's more than enough friendly local facilities nearby. I would highly recommend this stay.
