We stayed for 5 days in Leyton, Debbie being our great host. Debbie's place is so conveniently located near a lively area at Leyton (just a few minutes' walk to the main street of Leyton - High Rd. and a shopping cluster incl. ASDA hypermarket, a NEXT store and places to eat). We also visited the Greek orthodox church nearby for the Sunday service. We even walked to the Westfield Stratford Shopping Centre through the Olympic Park and East Village, which is less than 30 minutes of nice walk.
The underground station is 3-5 minutes away.
The flat is a tidy, spacious and dwelling place, well suited for families with kids. It is located in a gated community, so it is safe to leave your kids explore the yard ang make friends with a couple of squirrels living there :). We cooked a lot; the kitchen is well equipped.
Overall, we strongly recommend Debbie's flat at Leyton for family or small groups of friends. We will try to book it again for our next trip to London if Debbie wants us :)
