Nothing that special about sofia. Nice people but nothing particulary noteworthy about the place. Liked the bulgarian countryside and little villages. Roads werent great. Very hot day and tiring ride into romania. No problems with border control. Roads good and countryside reminds me a bit of uk. Flat and green. Rode through bucharest. Busy and more modern/western than I expected. Found camp site with little bungalows for 20 euro a night, wifi, showers and they sell beer. Result. Transylvania pass tomorrow.
