Hassle free from start to finish. Instant online confirmation followed by friendly on time drivers.
Mixed feelings. Very professional but had scheduling problem. We asked to picked up an hour later but were told we couldn't be due to the need to pickup others. When we were picked up there were no other stops for others so we ended up arriving 2 hours earlier than needed. I wish they would have been more flexible on scheduling.
Quick and affordable. The driver was very friendly and right on time. But please be aware that booking through Viator it took some time for the booking to get through to the local tour operator to receive my details. At time of booking you're not given a pick-up time from your hotel, so you have to call the operator to get that and when I first called they had no record of my booking. It only came through 10 minutes before they closed their telephone lines (for the day). And I had to leave the next morning. So book it at least 36hours in advance.
