The pictures of the room in the Airbnb app as of time of this review, were from when the room was renovated, I assume, as it definitely now has some visible aging.
In reality, it needs maintenance. The mattress was not very comfortable: when I sat on it, I could feel some springs and dipped all the way to the base. Laying down was not as bad but not very comfortable. Apparently the host never got any complaints.
Also, the room need more ventilation as it smelled.
The bathroom also need some cosmetic maintenance.
The single pane windows did not help this December as the temperature outside was below freezing at night during our stay.
The Battersea park nearby was a gem.
Bus/subway location nearby helped getting to London center nicely.
