Spanish guy 22 years old wants to share a twin room in London

hi guys!! I'm a spanish guy and I'm doing an Erasmus internship in London from 28th June to 30th September and wishing to stay there for further time if economic situation allows me to do so, I'm looking for a nice room partner to share a twin room in a residence (as cheap as it can get) by that time.I want to get to know new people who are interested in sharing a room with me because I haven't been able to keep in touch with people who are planning to accomodate there in summer.
I can describe myself as a nice person , I'm no controversial at all and I like keeping everything tidy, on the other hand, I would prefer to share a room with people from other countries so that I can get to practice my English skills, I can also speak a little bit of french, italian and chinese, just so that you know.

P.D.: Maximum price means 120-150 pounds per week
Looking forward to your comments
