We had a short 3-night stay in Amy's place and loved it. The flat was spotlessly clean and really tastefully furnished. The kitchen is fully equipped and the bathroom is huge! Nice shower and great WIFI. A missing screw meant the bed had an annoying creak but we have informed Amy and she said she will repair it ASAP.
The area is great. One minute walk to a lovely park, great for a run or stroll. Tesco Express 10 mins walk, tube station 15 mins walk and Walthamstow Village 20 mins walk. All in all a great Airbnb choice for your visit to Walthamstow.
