Journeys London East Hostel

I stayed there when I first arrived in London, before I found a flat-​share. It was early July and everything was fully booked, so I just booked this hostel for three nights, for just over £10 a night.
I arrived in the middle of the night because my plane was very late. And then the nightmare started: the hostel was very far out of Central London (although the website said differently) and the cab driver couldn’t find the place. He didn’t want to risk dropping me in the area because he said it was very dangerous and I wouldn’t last 30 minutes on the streets Errrrr not a good start.
When he found the place, he kindly went in first to check it was a hostel because the front door looked like it was a clandestine pub or something. The receptionist a tall blond guy — was extremely rude and told me off for arriving so late (although I had called beforehand to say my plane had been delayed and I would be arriving late). I apologised and said we had had trouble finding the place because it was much further out of London than I thought, to which he replied It’s not my fault if you can’t read a map. Asshole.
The place was filthy, I wouldn’t even touch the walls, doors and I wouldn’t take my jacket off to go to bed. I was staying in a 14 bed dormitory. To be honest, this should have been a 8 bed dormitory at most. I don’t even know how they managed to fit all these bunk beds in the room. There were open rubbish bags everywhere in the corridor and rooms’ floors and the smell was vile. On the terrace, with a view on the overflowing and smelly disposal container, was an ashtray that hadn’t been emptied in month, with cigarette butts covering the whole floor.
The next day, I couldn’t even shower because the bathroom was so gross you wouldn’t take your shoes off. There was 1 shower per floor, an a queue of grumpy people in their underwear waiting in line in the corridor.
I went down to the reception to tell the guy that I was going to cancel the other 2 nights I had booked and he refused, saying I had to give a 24hr notice for cancellation. I managed to cancel 1 night of the 2, ran out of that horrible place. After a whole day of running around London, I found a family hotel in Paddington. I paid £100/​night for that but I would have paid much more to get me out of that dump hole in Woolwich Arsenal they have the cheek to call a ‘hostel’. I’m just grateful that I could afford to leave that place, not everyone is as lucky.
IF YOU HAVE A CHOICE DO NOT GO THERE!
