Martin's boat is a lovely cosy space, and staying there is a total change of pace. We live very nearby (10 minutes by car), but even then, it feels remote and disconnected enough to be very relaxing, but is easy to get to and has all the necessary 'accessories' you need to not be a survival expert. Grilling on the deck in warm weather was lovely, and the private sauna boat is definitely recommended—even in the rain and wind it is an exciting and cosy experience to be on the boat.
Martin was friendly and attentive, and definitely doesn't come across like a 'commercial' host as many do—it makes the successful building of the boat and the excellent furnishing even more impressive. Congrats! We would like to come back.
Tip: don't underestimate the amount of drinkable water you should bring (we needed at least 6 litres for a 2 night stay, 2 people, including drinking, tea, coffee and cooking pasta). Bring extra just in case.
