Reliable every time we've used them and decent value compared to other transfer operators. No issues with the vans - modern and appear well-maintained. Only reason for not giving them 5 stars is that we had arrivals and departures from Terminal 2 at GVA this year and Skiidy required us to walk to, and from, Terminal 1 where their desk is, and then all the way down to the car park beyond the train station. Since Terminal 2 at GVA seems to be a permanent thing, it would be a much better service if Skiidy could offer an option to be picked up from/set down to Terminal 2 as an alternative to Terminal 1.
