I booked for a Turistik tour online and the bus never came to get me. I cannot really comment on the level of service on the actual tour but it is terribly unprofessional and inconvenient when you have planned to go on a tour and then they just miss you on their list. I could not get hold of their call centre and when I eventually did, they did not seem particularly apologetic. Apparently it was "an issue with the bus" - but the same said bus did fetch other passengers that morning according to hotel staff. They offered to do a refund so I am hoping that there are no problems with this. At the very least, they could have offered to do a private tour due to the inconvenience. Based on the poor administration, I would not even consider using this company again.
