Graduate professional for a room near Letchworth

I’ve just got a new job near Letchworth after travelling for the last few years, so I’m looking for somewhere to live with a reasonable commute. I’m friendly, easy-going and always up for being social, but also happy to chill out after work. I’m clean and tidy and would ideally like to find a double room in a house with other friendly people around a similar age. More than anything, I’m looking for a place that feels like a home and where I can get to know my flatmates and make some good friends.
