Marcus and Vicky are perfect hosts, we felt very welcomed in their home. Store and access to public transportation are close, tube takes you to main sights within 30-40 minutes. Would stay there again!
Note: careful with National Express to Stansted Airport (bus stop just outside the apartment) - although we heard only good things we almost missed our flight because the early morning busses were canceled or full (we bought tickets in advance!); make sure to schedule enough time between departure and flight.
