Nanny for One month in Ithaca

We are looking for a live in nanny for one month for our one a half year old twin girls. We will travel to the island of Ithaca on July 25th, where we will stay with my husband’s parents, and we will all be helping each other with everything. We will stay in a house by the sea with a big garden, and probably will go every day to the beach. The nanny will have her own room and bathroom. Must be comfortable with dogs as we have 1 Jack Russell terrier and 1 Labrador, both are friendly and child friendly. The nanny will be expected to help with a bit of everything child related, alongside the mother and mother in law.
