Enjoyed Borovets very much, although we did not see it in all it's glory due to the lack of snow. Thought it was in need of a spruce-up but then again what Bulgarian resort doesn't.
Conclusion?
Prefered it to Bansko - but as you may have guessed Pamporovo is still No.1 for me and probably always will be.
Had a great time and can see why many people love it.
