I booked a 1-day tour from Bucharest to medieval Bulgaria and everything went wrong. First after receiving the confirmation of the booking, after a few hours I received another message saying the tour was full and postponed for 2 days later!!! We cannot trust when they claim to give real time confirmation on availability. Then the tour itself was a nightmare- for a tour of 12 h we spent more than 9 h inside a mini-van!!! The tour guide (Carmen) was a fraude (in this tour). She provided almost no information. When we arrived to two of the planned sites, she only mentioned a few basic facts and left us on our own! In total maybe she spoke for 10-15 min (out of the 12 h). The driving was very dangerous (e.g. 60-80 Km/h inside villages where the speed limit was 30-40, or more than 150 on the roads while the driver was chatting on the phone). The worst tour ever.
