The location of the boat is excellent -- we'd grant it 6 stars if there were that many. It's right by the foot of the MAS, in a trendy neighbourhood with plenty of stuff to see, drink and eat.
We were a party of six and had the place to ourself, but this boat has plenty of space for a bigger cohort, with a large and comfortable living room. The rooms/beds are boat-size :) There's plenty of space on the deck to sit and relax in smaller groups.
