Alessandro's flat is conveniently located near two underground stations (Victoria/Pimlico) which will give you easy access to the rest of London. We enjoyed our stay and found it easy to navigate the area.
A few notes:
-The stairs to the kitchen are VERY steep, so consider this if you have knee or back problems
-The shower is quite small, so larger folks might have a hard time turning/moving
-No frills, we had one towel each and needed to go to the supermarket to get toilet paper and paper towels
-Alessando did provide a power converter, which was helpful. We also had wine waiting for us on arrival :)
