We travelled from Bucharest on 15th via vama veche.
We stayed in room A-2, a large room more then adequate for us four. The room was clean and well prepared, if a bit odd. Surround sound flat screen tv but no kettle! Only a broken microwave.
The disco across the bay in sunny beach is the bane of nessebarians; it goes on until the early hours (7am, fri and sat) and the noise travels. Bring earplugs.
Breakfast is served with a smile but don't expect the works. It's functional, but fine. Our kids loved the pancakes.
Staff are friendly, willing and hard working but their measure of what good looks like isn't very sophisticated. Not their fault.
I recommend Trinity. We stayed 5 nights, extending from the original plan to stay only 2.
