You are about half a mile from the main nightlife which is centered around the Perelik area. DJ's - Daks - Spyders - White Hart - Apres Ski Bar all have a great party atmosphere and go on until very late. (up to 4am).
Better to get a taxi rather than walk as it's very icy at night.
Sam I am at the same hotel from 02 - 09 march, only 24myself, coming with a group of 20+ year olds, I hope to be out most nights.... were a short walk away as pete says... only 5 mins to daks, and it a good night in there, the main bars 5 mins more, you'll have a wicked time, just pray for cold weather!!!!! all the best for your hols
