Thanks for Anna, my family had a great time in London. The flat is exactly as pictures, warm and clean! It is one of those home that you can feel how much love and efforts owner have put! My parents enjoyed the surrounding a lot as well. Considering the convenient communication, very responsive and helpful host, and comfortable living, I'd definitely recommend people to stay there!
If anywhere I have to suggest for improvement. I'd say the wifi was a bit unstable. It even disconnected in one night. It could be a special case though. I would give my best wishes to Anna and Roman! Thanks again!
