We really liked Salines Garden.
Pros:
Inexpensive
Can get room with kitchenette
Jean-philippe is very helpful (will meet you at the ferry/airport) and fun to talk to.
Breakfast included (and having breakfast with the other guests was always fun, and a great way to find out new things to see on the island.)
Very close to Saline beach
Cons:
Does not have a view of the ocean
Breakfast is not exactly "healthy" (bread and jams, croissants)
Has a long, very bumpy driveway (not a problem, just have to drive really slowly.)
Advice:
Get a cottage with a kitchenette. We had the "Cap Ferret" cottage. One of the other guests said their kitchenette (which is outdoors) was infested in mosquitoes. We did not see any at all at our kitchenette, I think it got the breeze a bit better. Overall, we hardly saw any mosquitoes on our trip, actually.
If you're used to have a breakfast with some nutrition in it, you'll want to think about adding to what's served at the table. There were a few of us there that were bringing more items to the breakfast table.
Overall, we were very happy with where we stayed. If and when we come back to St Barts, I think it would be very likely that we would stay there again.
