Hello everyone! I've always had good luck posting in this subreddit so I thought I'd post again. Me and some friends will be traveling Europe this summer, and our first two stops are in Edinburgh and London. The last time I stayed in London I ended up in a really crappy hostel, and I've never been to Edinburgh, so I thought I'd see if you guys have any suggestions. I'm really into party hostels, places that have events, maybe their own bar like the St Christopher locations, and are a really good time.
