Room 5 is indeed a clean, cozy single because the room is a bit small compared to double so it gets warm really easily and quickly. If you're someone like me who is not accustomed to the low temperatures of London, then it's a good one.
The shared kitchen and bathrooms are clean and well maintained. Even though you'll have to share the kitchen with 5-7 other people, you never feel like you have to fight for it. Same is the case for bathroom.
Emma is friendly, helpful and accommodative.
The location is unbeatable. You're just 10 mins walk away from the station and the mall!
