Anglia Ruskin University (APU)

Language courses were given by very qualified teachers although they did not have a degree in translation

If you are not used to the kinf of weather or food like in England, mayb it will be hard for you at the beginning. But just take it easy, meet many people, work (it's very interesting to work in Cambridge and it's good money), do many activities (societies at the Uni, sport, ...) and have fun!

my experiences are good, but soem of my friends are not satisfied with the facilities

Cambridge is plenty of pubs and nightclubs and there are many international students parties every week. I'd recomend The Junction, a very good nightclubs with famous/good Djs and venues od electro/hip-hop music. But as you know probably, in England pubs and nightclubs close very early so another alternative to party is to go to a "house party". House parties are private student parties that take place in shared houses and anybody can go as long as everybody bring his own drink. It's a bit individualistic, but a very good way to meet people.
