Based on 285 reviews analysed · Last updated · How scores work

The short version

Based on about 160 recent Google reviews with text (from 287 kept ratings, many of them stars-only), this off-site shuttle desk is mostly praised for quick pickup, quick return and clean, newer cars. The main risks are being refused the car if you do not hold a true credit card, and disputed charges after the rental (damage, fuel, tolls, extra days). Staff attitude and breakdown handling draw repeated criticism, and web evidence is mixed and often undated.

What travellers flag

Red flags (4)

  • Around 17 recent reviews describe disputed post-rental charges: damage said to be pre-existing, fuel accusations, toll or one-way fees, an extra rental day, or a deposit not yet returned. Amounts mentioned range from about €60 to €500. These are customer allegations, and similar complaints appear in a late-2025 forum thread.tripadvisor.ca
  • Several recent reviews report poor handling of breakdowns or warning lights: waits of about 3 hours for a tow that did not come, no spare tyre, slow or unavailable replacement cars, and unanswered phone lines.
  • About a dozen reviews describe counter staff as rude or unhelpful, often during card disputes, and at least 3 report pressure to buy the desk's own insurance despite cover bought elsewhere.
  • Several reviews report problems outside opening hours: the office opens at 6am and the shuttle starts then, so early returns face a crowded street and cars left outside. One family arrived at night after a delay and found the desk closed.

  • About 25 reviews describe cars that were new or nearly new and clean.
  • When there is no dispute, deposits are reported released within one to two days, and toll costs are taken from the deposit.
