We were a group of 5 and booked a 16 seat private taxi for four days. The 16 seater, honestly, would be rather compact if to sit 16 person, I'd say, 12 or 13 at max, without luggages. We notified Jane in advance of our itinerary, as to avoid the fuss of communication issues with the driver; all the drivers understood English, while one was more fluent, anyhow, our trip was totally fine and smooth!
Jane was very helpful, she always replies quickly and was able to do itinerary amendments precisely.
The price though, honestly, I think it's a little high comparing to the local Taxi costs, but to avoid the fuss, especially for groups, it's well worth it.More
