The staff was amazing, very friendly and nice. Cool location and nice bar downstairs. I loved the area (Borough Market, London Bridge, Themse, etc.)
Sheets on bed were clean, matress quite thin but still good to sleep on.
But, ... towels had to be paid for (though it didn't say anything about it online). Bathrooms were dirty and small, not a lot of space to get changed or anything. And not a lot of extra storage in the shared dormitories. Another - bigger- room to hang out, sit and eat would have been nice. The breakfast was just 4 Pounds but also didn't offer a lot.
You have to use an extra app on your phone to unlock the entrances and doors, just fyi in case you don't have enough capacity on your phone.
It was no problem at all to leave your luggage there, you just need extra cash to pay for lockers. Good idea!!
