Bulgaria offers pretty much every kind of accommodation option you can think of, from spartan mountain huts to the most opulent five-star hotels. Accommodation is most expensive in Sofia and other big cities, notably Plovdiv and Varna. Elsewhere, prices are still relatively cheap by Western European standards. If you’re travelling independently around the country, one indispensable publication is the Bulgaria B&B and Adventure Guidebook (13.50 lv) published by the Bulgarian Association for Alternative Tourism, which lists sustainable, family-run guesthouses all over Bulgaria. You can buy it at Zig Zag Holidays in Sofia.
