Bravo Artex!
I went with Artex on wonderful bus tours: "Rome-Paris: two eternal cities", "Treasures of the Empire + Switzerland". The tour program is well developed, the guides Lyudmila Danko and Vyacheslav Stupnikov are very attentive and responsible, the hotels along the route are quite comfortable, given that I’m not going to stay at the hotel at all. There are no complaints about the tour operator - only gratitude for a well-organized vacation.
