We stayed about two weeks in Humminbird 6.
Luckily we had rented a car for whole period, it made things much easier.
There is quite good public transportation and bus stop just about 100 meters from the house but still I recommend own car.
Nearest supermarket Jordans is about over 1km from the house. Few restaurants in walking distance (very local Wendy's), nice but reasonable priced fine dining place Karib, italian El Tempio (near by Jordans supermarket. We got here two times: first and last).
There is really no walk paths in Barbados so walking in the evening by the road is something you should consider carefully without doing.
Note that Jordans is not open on Sundays, nearest supermarket open on Sundays is in Holetown (15mins drive to north).
Beach is in walking distance but downside of that beach is that there is no bar or any kind of service point at that beach. Thats because all inclusive hotels seems to be not allowed to sell drinks... more
