Martin's B'n'B is a very nice place to stay on the island even though I had some minor difficulties to find my way. If you are carrying big luggage with you I recommend to use a cab/taxi.
Everything was very uncomplicated and everyone was very friendly and familiar. If you want to be on your own that's perfectly fine, but if you want you can also enjoy the community with other guests and your host. Nice convivial gatherings through out the day/week.
