Very good hostel : clean (which is unfortunately quite rare in this type of accomodation), pleasant area bar, friendly staff, good breakfast for only 1.50 pounds (several cereals, coffee, tea, butter, jam, yoghurts, fruits ..). Good location : London area 1 and quiet street. The only improvement to do would be to add some trays in bathrooms to put down your clothes. I definitely recommand this hostel ! ;).
This hostel has large rooms and kitchen (you have to bring your own food for breakfast), pleasant bar. As for many hostels, don't care about the cleanliness in bathroom : the floor is quite dirty, there isn't any tray to put down your clothes. More over, it's impossible to change the water temperature in the shower ... unbelievable ! Another point : it's difficult to sleep because the bar and the street are too noisy. Finally, the location isn't good if you want to access the center of London.
This hostel isn't extraordinary, but not bad : the staff is cute, the place is quite enjoyable, the beers are tasty and no too expensive. I didn't like : the beds are not comfortable because of their thick mattress, the breakfast could be more diversified (fruits and yoghourts for example). Especially, toilets and bathrooms are too small ... and quite dirty.
