Very nice. I rented VW Sharan for one week. No problem at all :)
3 days rental for 2 cars, 5-7 august / reservation from Corfou by phone 2 days before, no deposit needed because agency was comprehensive.
Member of agency came to ferry-station to pick us to their agency.
One of the car (7 seats) was dysfunctionnal : the agency came few hours later in the evening to Ksamil (where we were staying) to change the car : no extra-charge, and partial refund because the replacement car was 5-seats.
Good service, very helpful, good english-speaking.
An upscale business
Lovely & easy to deal with - best contact is via email before you travel.
