Can't say enough positive things about staying on Derk's houseboat, but I will try. It was charming, warm, inviting, unique, comfortable and simply amazing. And wait until you tell your friends--people think you are quite frankly the coolest person ever! (Not that that matters!) :)
Stayed her with my daughter and we both agreed we wanted to move right in. It was that delightful. I'd stay there again in a heartbeat. And I think it would be incredibly romantic, if you are with your significant other. Derk was great with communication and super helpful.
The only negative was we only stayed for two nights. I'd happily stay there for a month!
