Looking for a single or double room

I'm a 29-year-old marketer. I'm moving to London in Aug./Sept. for work and to obtain my MBA and I'm looking for a single or double room.

I'm hoping to move into a comfortable flat with people my age who share similar interests such as fitness, travel, films, and rock climbing. I'm a very active person and would love more friends to join me at my run club at Running Late or at yoga/pilates classes, but also love a night in cooking dinner and chatting/watching some telly together.

Since I'm 29 and used to a working professional lifestyle I'm very hopeful to avoid going back to student housing and hope for a relaxing and cozy living space to call home and will be more than happy to get together with flat mates for outings or evenings in.

I am available to move from mid to late August or September!
