Hi Antonio.

Liverpool and Manchester both have big student populations, and rents are pretty reasonable.

Swindon and Reading are both on the "M4 Corridor" west of London (access to Heathrow), and both are somewhat expensive (Reading more so, I believe). The whole area has essentially no unemployment, and many companies of all types are located there.

The cheapest cities (where there is a possibility of finding work) are generally in the North - Liverpool, Manchester, Leeds, Newcastle. Try also Nottingam, Leicester, Birmingham in the Midlands.

Here's a place you might start looking for an
