The Bulgarian Capital Sofia is fantastic value for money! There are also a whole host of free tours for you to see the city including a free walking tour, free bike tour and a free hiking tour to see Boyana church and Boyana waterfall. Rila Monastery, 2 hours from the city, is a UNESCO Heritage site as should not be missed!
