The airport is small.
We landed at about 10.30 (bulgarian time) and arrived at our hotel at midnight.
It took us about 30 minutes to get through passport control.
It took us 35 minutes to get to sunny beach.
On the way back it took us about 10 minutes to hand in our luggage and go through passport control.
There is a small duty free shop and a bar.
We arrived at the airport at 10.00pm and the plane took off at 11.15 so there was not much time to hang around.
