Tidy, clean and secure place to stay in London. It might be difficult for long term stays as there is limited space and facilities, but for short term stays it's absolutely fine.
The room is next to the bathroom so you'll be woken up a lot if you don't have ear plugs. Also, take an eye mask. There's a glass window above the bedroom door, which means any time anyone wakes up during the night and turns the landing light on, you will get woken up and you will probably have to get up to turn it off.
