Great stay on Juul's boat. Very unusual to be sleeping below the waterline in the WW2 concrete cargo boat. But you wouldn't know it as it is decked out as a small apartment with double and bunk rooms and all modcon facilities. As we were there on November the heating was on and kept us very warm at near zero temperatures. Juul was very responsive by message in the lead up to our visit and met us on the day to show us around the boat. He recommended a local restaurant called Oceaan for the first night, literally 3 minutes walk from the boat with tasty food and local atmosphere. It's very easy to get bus or tram within 10 minutes to the city centre.
We'll be back one day!
