Easy to navigate via underground to most parts of London. You get what you paid for, was mostly clean. I was out most of the time so I pretty much only used the place to sleep, so I wouldn't say I cared a lot about the accomodations.
Walls are quite thin and you will hear your neighbors.
There was a door across from the beds that didn't lock and opened to a space that was like an underground room but had light peeking through to an area outside, not sure if it was big enough to let a person down into the underground area but it did make me leery and nervous. I contacted the host and he sent someone to put a latch on the door but the latch on the door still wasn't locked and I did worry someone could come in.
Also bottom shower door on the left hand side was off rail and I did let the host know. It didn't affect showering but it wasn't fixed in my time there.
Also the flat would have strange smells like sewer from the bathroom at times and I noticed in a previous review someone mentioned it, so it must be an ongoing issue.
If you want a cheap place to stay it's not a bad deal. In the future though I would pay a bit more if I planned on being inside more.
