Excellent location, a bit dirty, rude staff
The good: The location is great. It's less than a minute walk from the Tube Station, walking distance from touristic attractions, cheap restaurants nearby.
The bad: Definitely not the best showers I've seen. The building seems old. The beverage vending machine wasn't working, so I had to go to a store outside to buy something to drink.
The ugly: I stayed in a shared room. At 3 a.m. a staff member opened the door and started shouting to two guests guests. Someone from the room had called the staffer because two guys were smoking inside the room.
The staff and the two smoker guests start shouting, the guests denied they were smoking (they were though). They shouted for like 10 minutes and demanding them for them to pay a fine or leave. At that point everyone on the room had woken up. The staff member then tells to everyone in the room "If you don't tell me who was smoking ALL of you will have to pay a 50 GBP fine" and that "if we didn't have money that's why they had an ATM in reception". That's the worst thing they could have said, telling me and the other guests to pay a fine for something we didn't do.
Finally after telling the two smokers that he would call the police if they didn't leave, they finally left, paid the fine, returned to sleep again and said "I'm sorry to everyone"... The staff member didn't apologize for waking all of us up.
