The place was easy to find and very clean. I had a problem with the working heater not being strong enough to heat up the entire house (as there was a heater in the main living room which was out of order), but eventually solved it by sleeping in the room nearest to the working heater. You may have a problem if there is all 6 guests in the same house..
Also, just wanted to add that the supermarket nearby has very limited options and I would advise that you stock up before coming to Coles Bay, as the town is rather quiet during non-peak periods but is otherwise very safe.
