We had a great stay at Fi's flat, and it was located perfectly for our needs. As we had a few shows at the O2, this was so convenient for us.
The flat had everything we needed and Fi was great in welcoming us and making sure we got there correctly. There are shops nearby if you need to buy anything, and both the bus and tube is nearby making it easy to travel around.
Really recommend Fi's flat, thanks for a good stay!
