En suite room available for August

An en suite room available for the whole of August at Beaumont Court accommodation (provided by Unite Students). Great location: 5 minute walk from Camden, 5-10 minute walk from Mornington Crescent Tube station, 15 minute walk from King`s Cross.
The kitchen is shared with 4 other people living in the same corridor, all of whom are students (mostly doing their PhD). The kitchen is very large though and other tenants are very nice, so there have never been any problems.

I pay £230 per week, but I have to leave London for the summer. So, I would like someone to replace me over this period even for a smaller pay.
