Sophie's flat was very quiet, which we really appreciated after a long day travelling. We didn't meet Sophie personally, but she was available if we had any questions. I would recommend taking a taxi if arriving with luggage when using the Underground. There's a mini cab station about a block away from Bethnal Green Station and it costs about 6 pounds. If you need to go to Paddington Station, it's about a 45 minute taxi ride, and costs approximately 20 pounds. It costs about 40 pounds to take a taxi from the flat to Heathrow. There's a mini cab station about a five or so minute walk from the flat, and you can advance reserve a taxi.
