I really enjoyed my stay here (2 weeks). The apartment is well positioned on beautiful leafy suburb - very quiet but also close to shops and transport. Links to the rest of London are great, with the Bakerloo, Jubilee and Overground all within an easy 10 min walk. The room itself was super clean and comfy, with loads of natural light from the garden behind.
Unfortunately didn't have chance to meet Xristina personally, but she was always responsive to message and checked up on my stay regularly. It was her housemate who helped when I arrived. He was really friendly and helpful throughout my stay.
Highly recommended :)
