Had a bad experience with this company on our recent trip to Alonissos.
We are a generally easy-going couple in our 50s and usually hire a scooter when travelling in the greek islands. As long as the vehicle is 80cc or below, we have done this without problems on at least a dozen islands on the basis of my UK car driver's licence.
Despite making an advance booking with Albedo travel agency in Patitiri, agreeing a 50cc machine (mentioning the UK car licence) and leaving a deposit, the promised scooter was not available on the day with the previous hirer not returning the machine on time. This is understandable, although frustrating and as Albedo travel did not have an alternative vehicle we asked for the return of our deposit. Unfortunately attempts to arrange a hire at short notice with alternative hire companies was not possible.
Returning a couple of hours later to Albedo Travel as they suggested, a suitable machine had now been returned and was available but they were now unwilling to hire it to me on account of my UK car-only licence. The English lady in the Agency seemed to go out of her way to be awkward and the very brief apology despite leaving us hanging around was definitely unconvincing.
One to avoid!
