unfortunately the booked one was cancelled due to lack of interest. instead i was promised a tour the next day. unfortunately not the same one, an easier one that i wasn't really interested in, because i really wanted to ride a bike, i arrived it getting a bike, which i liked, was not so easy, ulrike, our tour guide, could handle it without any problems. she was really great, very nice, reported interesting things and funny. little tips gave extra. the tour was really ok, especially if you don't know rom yet, it gives you a good, quick overview with a light funfactor. i would have been more interested in the hidden places, which are unfortunately out of the way.
