We had a very pleasant stay and Sjef is a great host!
The ship provides enough space for 5 people and a very well equipped kitchen (including a coffee-machine - it's nice to sit at deck in the morning!).
Also there are nice (also vegan) restaurants nearby. Its a 5-minute walk to public transport (tram&bus). We parked at the P+R Zeeburg 1 for 1€ per day, remember to keep your public transport ticket, otherwise you won't get the discount!
