The studio is amazing and it is located in an equally amazing building. It once was a industrial building, but it has been turned into a real, though very special, home.
The photos give a real good impression of the place and we had everything we needed to have a great time.
As for public transport: during daytime there are plenty of options (maybe at night as well, but we managed to screw that up once). If you're not in a hurry: use the double decker to Waterloo Station, it is a great way to see a slice of London and the busstop is extremely close by.
In all: a great place and I definitely recommend it!
