I had a wonderful experience staying at Carla's flat in London. I arrived late on a Friday evening - Carla helped me with all of my luggage, warmed up a delicious bowl of soup for me, and made me some tea. I immediately felt at home and comfortable.
She provided me with great recommendations for restaurants to try and sites to see in the neighborhood; she also always made herself available to answer questions or give advice. The flat itself is bright and lovely, with a very spacious room with plenty of storage. I highly recommend staying with Carla!
