I stayed at the Vassilia Hotel (2 *), located in the very center of the town. Pretty cozy, tidy, the level of comfort is quite acceptable, friendly staff. The hotel itself is located in a pleasant proximity to the warm sea and the Old Town, the food is excellent - thanks to the half board.
On "duty" and business matters, I most often travel alone. You have to spend a lot of time in different countries, and sometimes you just want to be alone with yourself. The main issue for me when buying a tour is the speed of paperwork and the complexity of the service. And in this Tour4Friends seems to give odds to a number of firms with which I have already dealt.
