Hi Alice,
Not sure what you want to know, but here are some disconnected points.
Very good shopping centre. The home of Allders, and its last remaining store. A centre of business, UK HQ of Nestle, a large Philips building around which are constant eddies and mini-tornados.
Tramlink. You can get to Wimbledon within 20 minutes, but why ?
IKEA. You walk in and are logically met with an escalator. The car park is like a go-kart track.
To the north it merges insensibly and insensitively into the suburbs. Avoid West Croydon and environs at night although most bullets miss.
To the south, South Croydon, Purley, Coulsdon, and on up to the North Downs. the environment and house prices rise. Good night life in South Croydon, loads of good restaurants of all types.
It's not a bad place. Mitcham Common is close by and has loads of quiet secrets.
Have a good time when you come here.
