Room Jul-Sep For Visiting International Phd Studen

I'll be visiting Cambridge University Engineering Department as a Visiting PhD Student from my university in Czech Republic. I'm looking for accommodation for the three months I'll be there, starting July 1st and ending September 30th + couple days before and after that.

I'm not that picky about the state of the flat but I'd prefer housemates of relatively the same age.

I kinda don't know what to write here for character traits or something like that. :D I'm probably something like a curious introvert that prefers smaller groups? Banter in a pub with a couple of friend or watching a movie at home. Something like that. Never been good at describing myself. :D To be honest I don't really know how much work I will have at Cambridge so maybe all I will do for the 3 months will be sleeping and working. Or maybe not :D (I hope for the latter). If I will have more spare time I plan to do some film photography in and around Cambridge.
