Пост в Central London Area Rents & Sublets - CS Houses/Apartments/Flats/Roommates.

Hello my friends! My 21-year-old son Aloïs will be doing an internship in London from June 10 to end of September and I'm currently looking for affordable basic accommodation for him ( he will only be making £400 a month) or a free room in exchange of babysitting and/or French conversation classes. If anyone has ideas i would greatly appreciate it! He's a really sociable kid who loves sports, music and arts. Any pointers will be welcome!
