The Central Hotel Sofia was wonderful, great location - convenient to walk to main sites and take a metro to ones further outside the city center. The breakfast buffet was delicious with a good selection. Clean, friendly efficient service. The flights were good. The booking was smooth and detailed, I like the reminders to print and updates on any changes in the flights or trip. The ease of the website is great that is why I keep using TripMasters. I love the selection of hotels, flights, tours or what ever I need for a trip with detailed information.
