We can absolutely recommend this place! It is a nice old boat with a lot of soul and history. Sjef has been working on it a lot and made this a precious little gem. It is not a licked-clean 5-star hotel, to be honest - if you're looking for this, you are not the kind of person apreciating to feel, hear and smell the Spartacus. Very cosy and for me one of the best BnB places I've been so far.
And Sjef is just great - he is always there if you have a question, he is always helping and has some of the best stories while having a beer and bbq (yes, ON the boat).
It was almost 30° in Amsterdam and heavily crowded in the city - best idea to have a trip on the spartacus out to the Ijsselmeer. If you want to have a good time: Spartacus is the place to be!
