Pros:
1) All the boats are behind a secure electric locked gate.
2) Not much water movement when on the boat, so no "sea-sick" feeling.
3) Boats are quiet, so even though close together, couldn't hear their occupants.
Cons:
1) For most of our trip, the t.v. wasn't working - not a great detractor, but annoying nevertheless.
2) Missing fire alarm - not noticed by the reception crew, but was installed on the same day it was pointed out.
3) Pub/bar outside of the marina (about ~70m from the boats) likes to play music loud in the evening - not overly intrusive, but you can hear the bass.
Overall, it was a great trip - the boat was a novel experience, and would certainly hire/stay here again.
