Let's just say that Croydon is not somewhere you would go to for it's scenery - it is more renowned for its ugly 70s tower blocks than for it's few attractions - but most people live there for convenience.  Central London is in easy commuting distance (15 mins Victoria or London Bridge) and it's also very convenient for Gatwick airport with fast trains taking just 15 mins from East Croydon.  There is a also a good tram system, which connects Croydon to Wimbledon.  And it has a very good shopping area centring around the pedestrianised High Street and the Whitgift centre.  You can find all the usual chains including an Allders and Debenhams.  There is also an Ikea and Wing Yip oriental supermarket and other out of town stores on the Purley Way, just 5 mins away by road if you have transport.  For entertainment, there is a cinema complex on the Purley Way plus 2 other cinemas in the centre of town, along with numerous bars and restaurants.  Central Croydon is very lively in the evenings - Ibiza without the sunshine!
