Pros:
1. Good location
2. it's a ship, so it could be an unique experience
3. I like the inner decorations of the ship
Cons:
1. You have to walk along the side of the ship deck to enter the ship. IMHO, there's not enough protection since you can drop into water especially during a rainy day. I would suggest to add a hand rail to the outside of the deck.
2. During our stay, there were people sleeping in the living room couch very early. So staying in the living room is not really an option for you.
3. You room is very small (~ 10 sqm). The window is also very small (mostly likely smaller than your head) and very high. So to us, the room is very humid. Sleeping inside during the night is not very pleasant.
4. The sound insulation could be better. During the night, you can easily hear people snorting in the other room (not sure there door was closed though).
In general, if you want to have an unique experience, this might work for you. Otherwise, this might not be right for you.
