I got a 1 Mb broadband connection in Sunny Beach.
CableTel has an office in Sunny Beach at the main road in the Condor building near the post office. The office is hard to find, hidden inside the building.
The people at the office speeks good English.
They offer cable TV, internet and IP phone.
Their web page www.cabletel.bg
(press English from the main screen) has information on different packages (price speed etc.).
Be avare that some of the packages requires you to pay for 12 months.
The quiality of the connection is OK, (working almost every day).
