After several negative reviews regarding the alleged inability to pay with debit cards, I was worried, but the reality was completely different. I encountered a very solid and correct attitude of the staff. I hesitated for a while to accept the higher category motorcycle (Suzuki Burgman) instead of the originally reserved lower category, because I was worried about the difficulty of maneuvering on narrow roads. I quite often rent motorbikes on different islands and I usually prefer easier to maneuver smaller ones, but Sardinia is obviously an exception with a disproportionately better road network, like Corfu in Greece - that's why I really enjoyed the free upgrade to a higher category of motorbike. For a better feeling, it is definitely worth not saving on a few Euros and paying the highest insurance, the situation is much less stressful for the rental company and the customer. The difference in the rental price is literally negligible. Full marks for me and I will be happy to come back to you again.
