I do not recommend!
Recently I was asked through whom we order tours. And I said through Come with us. The last time it was a branch on Independence Square. I praised them and even gave them a phone number, which I now regret very much, because my opinion about Let's go with us, and even more so about their branch on the Maidan, has changed radically. There are many small travel agencies in Kyiv, prices there are usually 5-8% lower than in Let's go with us.
