Mid-long term term rent from 14th June

I am a dentist in Cambridge looking to move to London. I am currently exploring options with flats or shared accommodation. I’m a chilled housemate, love socialising with housemates to make it more of a home. But! I am very happy doing my own thing going out to fitness things and seeing other friends. Weekends I’ll be galavanting. I’ll also want to escape the city for countryside breaks every month or two. The ideal room for me is a double with an en suite but is that gonna be an arm and a leg? Currently not too fussy about location central ish is where I’m aiming! North of the river but wouldn’t turn down a good option south. Say hi!
