Anshu and Prayas' unit was warm, comfortable for a family of five; 45 minutes by train to London's main attractions, Uber 45 minutes/1 hour-ish and 35 to 45 Pounds.
The communication was easy and thorough from the very first day. Questions were answered promptly. We felt welcomed even before we went to the unit. Check-in and check-out was easy.
The home is big, eclectic, comfortable, warm, bright and is fully stocked with tea, sugar, soaps, shampoos etc. The beds are very comfortable. The bathrooms were very clean. There is a washer/dryer and a dishwasher which is great if you have been traveling for a while. And a small grocery store on the way to the trains.
Docklands Light Rail, train station is five minutes walks away. After DLR, you will need two additional trains Jubilee Line and then Northern Lines to get to Trafalgar Square or Buckingham Palace or any tourist areas. So to be clear, it takes three trains, 45 minutes to get to see tourist sights. Google maps should help you navigate walking, trains, and bus routes.
I would highly recommend this place and don't wouldn't let the distance keep you from renting this place. It is really comfortable spot for a wonderful holiday especially for large family.
