A poster went there last year and he wrote a trip report . Check if you can touch base with him via PM to get the coordinates of his taxi driver if IC does not provide or arrange for transportation.

You can use bank machines - there are quite a few banking branches of in that area - i don't know whether in Balaclava per se but in and around Grand-Baie you will see some - HSBC/Barclays/ MCB etc
