Had an amazing time in London and Serena's place was perfect for my stay. The underground is just a few minutes away and there's many restaurants and stores nearby.
Serena was kind and helped me with a few transport recommendations, she was always there if needed. Kitty was the most amazing grumpy cat I've ever met and wasn't difficult at all.
In short, I had a wonderful stay and would come back again. 100% recommendable.
