This is the largest room in a five bedroom vicarage. Much bigger than a normal double. I've been sharing my house with folks mainly in their 20s and early 30s for many years now. I normally have two folks in there. The housemate who moved out (Jonathan) was in a smaller room, but a change in circumstances means a much bigger room is now available.
I am divorced since my wife left me for someone else four years ago and my two kids visit about 40% of the time, but a change in 17 year old Jess's circumstances means she no longer needs the largest room.
Most of my housemates stay with me for a good length of time - Jonathan was here a good 18 months before moving because of a change in his work. Phil who is still here has also been here about 18 months. RIchard and Lindsay (a married couple who were here before) left to have a baby. Simon left to get married to his Swedish girlfriend.
There are three big communal rooms in the house - Living room, kitchen diner and dining room as well as your room itself
