Camden can be nice around particular areas and times, but it gets bustled and packed around the Camden Stables Market (especially on weekends!). But that’s mostly just the main drag area. Loads of colourful, decorative buildings with a great deal of shopping! You’ll find some of the most unique shops you’d ever see. There are cute little docking areas as well where the Regent’s canal runs through. It’s very Bohemian, I guess. I had a friend who lived near the canal, where it wasn’t crowded; it’s lovely and relaxed around there. I’d imagine the hostels wouldn’t be bad in Camden, but I really don’t know.
I’ve never really given travel tips, actually! I’ve lived in both Pimlico and Kings Cross in Central London, as well as East London so I’m quite familiar with places of interest, but I feel like anything I say would be sort of bias in that respect!
Even living where I did, I often took trips to Regent’s as it’s lovely in late spring through summer. And I think those are the best times to be in London, but it’s also flooding with crowds, so I couldn’t really say from a tourist’s perspective. It also depends on the purpose of your trip. There’s always sight-seeing, but there are many festivals held in different areas all through August.
Umm, can’t think of much else at the moment, but feel free to ask questions. I’d like to help if I could. : )
