Demi, Its as much to do with who you have as the participants / audience as where you hold an event, The gents toilets at Wadebridge Folk Festival Camp Site used to be a fantastic venue for a late night sing, the acoustics were second to none - and all would flock there 'cos it was ALWAYS good!
That was of course before the stinky portaloos that we have recently been subjected to - though it was a bit stinky! - and NOT the sort of place you could put the kids to sleep on the floor!!!!LOL
Are you meaning venue for a gig, session, folk club, sing? It could make a difference. I always prefer cosy and intimate, but you know all about me!!!!
