Advance
Sifnos is a small island in the Cyclades, and car hire is more expensive on this island than is the case on many other islands in the Cyclades. Notwithstanding this often the cars are old and relatively scruffy. The cars from Advance all seem new. The staff were very pleasant and pick up and return very easy. Also they have a policy of full tank to full tank. Much better than some of the others that say return with the same amount in the tank as at the start.
