Konstantin's home was very welcoming. We arrived early and he let us drop off our bags while we went sightseeing. He lives in a very quiet neighborhood with the train about 10mins walking distance and a cute area with restaurants, cafes and shops. It takes about 30mins to get to the center of London but easy to get there via google maps or ask at the ticket window. Everyone is super friendly. We had complete privacy even though we shared a bathroom. The home was nice and warm when we arrives. It was freezing outside. I didn't get a chance to see Konstantin and thank him in person. I wish I had! I highly recommend stay in his home.
