We higly recommend the experience on Helma house boat . Access via tram 7 or 26. Supermarket close to the boat. We had a great stay . Communication was kind , easy and fast and we enjoyed the 3 days in a "Real" house boat with a "soul". Nicely decorated , comfortable , Well équiped for a family of 4 and very peaceful during the night , away from the crowdy center ! You have Access to the complete boat with a nice terrace to enjoy your morning coffee as well as a beer after a tiring day of visits
Only warning is : due to the stairs (normal you are on the boat) it is not well adapted for elderly people or young children ... For us in was simply perfect !
