As above, avoid Oxford road, trick is if any estate agent lists the property as “West Reading”, avoid it, they don’t want to tell you where it is as it’ll be a ****hole.
Same goes for Whitley (anything West of Shinfield Road, or estate agents “South Reading” or “Shinfield Road”, if it was a nice bit of Shinfield Road they’d say Lower Earley which is also nice) , although that’s not quite as much a hole, I spent a year in Whilety Wood and despite living over the road from a drugs den (metal plates for windowns, CCTV on every wall, 2x above the door), gettign propositioned by crack ‘ladies of the night/morning/lunchtime/afternoon/evening because it’s Whiltey’ on the bus, and occasionally getting chased by ‘gangstars’ so off their tits it wasn’t a fair race. It was Ok.
Depending on what kind of accommodation you want Shinfield Park’s usually good for professional house shares as there’s a lot of contractors at Foster Wheeler next door doing Mon-Fri.
