I would rate this trip 4.5 star - good range of coverage, accommodation (in most places), activities and free time. The only reason why I would deduct half a star is because Santorini accommodation could have been much better and choice of restaurants for organised group dinners could also have been better vs going to a place where all the other travel groups go - took away the authenticity.
Stunning scenery and such weather! Despite a last minute itinerary alteration due to ferry timetable changes, thus was a well-planned, wonderfully lead week mixing somewhat challenging walks with sightseeing and wonderful fellow travellers. We sampled many local dishes in lovely tavernas and village eateries and enjoyed some very amusing moments. A great week.
I was the only traveller on this tour so I had a fabulous private introduction to Athens! Great to help me find my feet and see where I should spend more time during the rest of my stay. My guide was lovely, and it felt like we were friends hanging out rather than a formal relationship. This was my third day tour with this operator, and it really cemented my trust in and appreciation of the company.
