Nice and spacious flat with very clean bathrooms, stayed here for 5 days with my family. Roger was very accommodating and explained everything upon arrival. Wifi was also very fast.
Location of flat is a 10 minutes walk from Stratford station and Westfield shopping centre and like others have mentioned there's a Tesco Express nearby. Despite being close to the rail tracks you couldn't hear the trains when windows were shut which ensured a good night's sleep.
The free parking spot in the secured car park was also very welcomed.
