I thoroughly enjoyed my stay in Joanna's flat. Small, but comfortable and efficient, perfect for me.
The neighborhood was great. The tube was closed over the weekend when I was there, but no worries plenty of buses, one right on their block. And even with the windows open the buses are so quiet it doesn't disturb you.
It is also just a short hop or walk to Portobello Road in Notting Hill which was wonderful, especially on Saturday for the market. Go early!
