I found Christo pushed just that too bit hard for my liking! (No comment from you Andie!!).
I prefer Georgi, who didn't mind when I stopped to admire the scenery (what else?) and had lots of patience. His English is excellent and understood my sense of humour, which is often a problem even with english people. You can ring him on +359888 719210.
His nickname is Jaffa Man. Tell him Lesley said Hi but don't say you're a friend in case he runs away - I nearly broke his neck!!
