The train station is 12 minutes walk from the apartment. See the following map for the suggested pedestrian route. Timetables can be found at www.nationalrail.co.uk.
There are lots of pubs and restaurants in the town centre (follow the directions to the train station) or there are 2 very local pubs - both of which serve food (though the Windsor Castle has its kitchens open more often). Both are just a couple of minutes walk: turn left when you leave the house and at the traffic lights turn left for the "Pond House" or right for the "Windsor Castle".
You should find a number of menus in the bedroom cupboard. Several of them are within easy walking distance - including Ruchi for excellent Indian food (see shops section).
Opposite the Windsor Castle pub, there is a newsagent that also sells food and has long opening hours but there is more choice at a local supermarket (a recently opened 'Sainsburys Local" which also opens late) - see the following map. There is also an off-license, pharmacy and the Ruchi Indian take-away at the same site.
