Flat: This apartment had a definite "hostel" environment. When I was there, the living room was my bedroom, other Airbnb people were in another bedroom, and a third bedroom housed a permanent flat mate (a man). At one point, there were four people sharing the bathroom. And, the only shared space was the kitchen. Strangers were constantly coming and going. If you like this, then this Airbnb is great for you.
Security of the flat: Many people staying in this Airbnb didn't lock the front door to the flat, so it's not totally secure.
Location: Excellent. St. Katherine’s Dock is lovely and just a five-minute walk. The Tower Hill tube station is only five minutes away also, so the location of this Airbnb is great.
