Our stay at Sylwia's was very comfortable, quiet, and convenient. It is a 20 - 30 min metro ride from major London areas. Our group wanted to see life outside the downtown areas while saving money and "commuting" in.
Because it's the last stop on the line, you're guaranteed a seat outside rush hour. There is a Costa Coffee, Tesco, & shopping mall within walking distance so you never really "need" to go downtown except for your sight-seeing. The trains behind the house are whisper quiet. We even saw an acrobatic fox twice in the back garden, which I've never seen during a hotel stay!
Good variety of take-out food up Hoe St. No laundromats nearby (or any open past 7-8 pm), so make sure you have time for your clothes to dry if using the washer (you'll need plenty with the cool temperatures). Plenty of hangers around to help with this.
Sylwia was a really great host - check-in was smooth, everything was spotless, and she left a snack/drink pick-me-up in the kitchen perfect for those flying or taking the train in. All the appliances were top-notch and 4 people slept comfortably and with enough privacy that we wished we lived there! We loved our stay!
