I liked this modern boutique hostel for the great private rooms. Some friends stayed in the dorms and they were nice too. Super design and fun atmosphere. The staff were really nice and helpful with all the questions I had.

I've never stayed at to this place, but I lived next door to it and only ever heard good reports about it. It does an English language pub quiz on Mondays which is good. The bar is really expensive though. There are plenty of pubs nearby that sell drinks for much less.
Is this your business?
