Not stunning. The flat is in a little ally on the top floor of a building that is not London’s finest. Containers for rubbish collection sit infront of the entrance. But safe enough and london south of the river is always a mix of buildings.
It works well from location point of view if you like the vibe of Borough market and the promenade on south side of the river (close to the Shard, Tower of London, Tate Modern etc).
The space is well distributed but the balcony not worth bothering with, except to have the door open if you like fresh air.
Beds are smaller than appear in photos.
On a hot day the top floor heats up a lot so you really need the air conditioning on (not something you would normally expect to use in the uk)
Watch out for the cleaning fee as you evaluate your options
