We stayed at Nettle Bay about 6 or 7 years ago and there are some things you will need to know:
1. you will need a plug converter and maybe a power converter. The plugs were round and we needed a power converter for things like our phones so that we could charge them.
2. The unit we were in had no phone.
3. The unit we were in had limited cable TV and all but 2 channels were in French. I think we only had 6 o 7 channels in total.
4. We had to check in at the Mercur (sp) across the street and no one there spoke English so check in was a problem.
5. The unit we were in had a safe but no one could provide us the locking mechanism so we had no safe while we were there.
6. As mentioned, their beach had lots of glass in it so you will need water walkers to put on your feet.

As I said, it was at least 6 or 7 years ago so things may have changed.
