I used this service a couple of times and I am very satisfied with the rates and accuracy:
https://crypto.bg/.
How to buy bitcoin:Choose bitcoin amount
Enter your bitcoin address
You will receive payment details
You will pay via ePay/EasyPay/FIBank – done!
How to sell bitcoin:Enter the amount to sell
Choose payout method
Send the bitcoins to specified address
After one confirmation you can get your money
You will be paid via ePay/EasyPay/Bank Transfer!
Of course there are 2 ATM, but they are only in Sofia and the rates are higer.
