The atmosphere is great! It was also surprisingly clean, with nice toilets and showers. I have read some people saying location wasn't very good but I thought it was just fine. It's close enough to the center. The only thing I would recommend is to bring a lock for the lockers and make sure you lock up beause anyone has access to the tent. And also bring earplugs since that many people in a tent can get loud. Other than that, great hostel!
Hostel is in a not so nice area but it's relatively close to the center. Staff are very nice and helpful. Hostel is clean and atmosphere is nice. There's a huge lounge area with lots of kitchen space that you can use
Hostel is nice and in good area. However, it's under construction. I was only there for two nights and it was very annoying. No air conditioning so extremely hot at night (but London is usually not too hot so it should be fine most of the time) no lounge area or nowhere to hang out outside of the rooms, which sucked. Hostel is In a neighborhood that's its extremely loud. Good if you like to party but if you wanna get some sleep probably not the best place to stay at.
