I chose Alessandro's place as I was only in London for one night and had to travel on further from Victoria station - so the proximity to it was my number one priority. It really is a short walk and I can highly recommend the area (restaurants and supermarkets nearby).
There was a slight issue regarding the booking, but it was quickly and proactively resolved by Alessandro.
The Airbnb was very clean, and fully equipped (e.g. kitchen utensils, just enough food for breakfast, and a charming touch of a bottle of wine).
I would definitely seek one of Alessandro's places upon another visit to London.
