Union Ivkoni London Sofia recent customer reviews
Enjoyed the experience of travelling through Europe by road. Considering the coach went from the UK to Bulgaria, the coach drivers were not forthcoming in speaking English for passenger instructions; only in Bulgarian. No toilets on coach - difficult as we were not told when and where our stops would be for toilet break/drink/food en route. No WiFi.

Good service but other passengers shouldn`t be allowed drink too much at designated stops - resulting in them requesting roadside stops to urinate!

Absolutely terrible. A 7 hour delay in Dover, as the company did not book the tickets, and as a result, got the times wrong. The drivers were chain smoking all day and night, which is illegal. We arrived at 2 in the morning in Sofia instead of 9 in the evening. This has made it very dangerous.
