I stayed there for one week during the easter holidays.
First I have to say: It really is a great guest house and there are only few downsides.
It's true what people write about the dogs. I was planning on going there alone first so I didn't mind (though I'm not a big fan of dogs either) but my colleague was rather annoyed and slightly scared. Maybe I should point out that there's a seperate area in the house which is for guests only and the dogs can't get in there... so you can avoid them if you want. Also there's no need to be afraid of them, they're huge but harmless.
I would recommend you to rent a car If you stay there, the town of Vieux Fort is in walking distance but I found the beach to be a bit too far off... maybe 40 minutes or something (only 5-10 minutes by car). We missed to arrange a car in advance (Brigitte, the owner, can help you with that) and weren't able to get one over the holidays. However, Brigitte and some other guest were very helpful and gave us a lift to the beach or the town centre every day (where you can take a bus to other parts of the island- also an intersting experience! Just beware that they don't run on holidays so you might have to take a cab).
Brigitte also picked us up from the airport and took us with her to Balenbouche estate when she went there to vistit her friends. She even gave us a lift to Rodney Bay one day, she really is incredibly helpful!
The breakfast was simply delicious. Bread, homemade jam, exotic fruit, vegetables, cheese, eggs... By far the best breakfast I've ever had.
The fridge was always filled with water and beer, wich you can buy for a very reasonable price.
The room was clean and cosy and the mosquito net on the bed was quite effective, I didn't have any bites in the mornings even when I left the window open at night for some fresh air.
There are two beautiful beaches in the Vieux Fort area, I especially liked Coconut Bay.
I also should point out that the view from the porch is stunning. You can just sit there, have a beer, relax and watch the sunset...
All in all I'd really recommend this place, especially if you're looking for a clean, affordable place that isn't crawling with tourists. The price is really reasonable, great value for money!
