to ask the lodger not to use the living room?

[EricNorthmansMistress]

I have a spare room and have advertised it to rent. I set the rent deliberately cheap for several reasons - to get interest quickly and also in order to find someone who won't mind not having the use of the living room. I said in the ad that they would be free to use it when I wasn't there (not very often! Apart from daytime). I also set notice period at one week. A guy has called (twice) and emailed and sounds very keen. He has a new job within walking distance and at the rent I'm asking he will be able to save a fair proportion.
He's coming over to meet us and see the room later. So AIBU to make it clear the rent is for the bedroom, kitchen and bathroom only? I don't want to be rude but I don't want a flatmate!

It sounds like the halls of residence accommodation when I was at Uni.
It's also something I know a lot of contractors look for when they are working away from home during the week (but going home for the weekend).

Oh for a room of my own .

I think it's fine for the week if he's working, quite difficult to stay in your room all weekend, but if you let him know in advance, it's up to him to say yes or no. Monday to Friday lets are quite common too, so that's another way of limiting the socialising times and having the house to yourself on the weekend, and plenty of people who work away from home in the week prefer them as they are cheaper and are not looking to socialise anyway. There's a website full of them and I always thought if I needed some money, but didn't want the intrusion of someone hanging around the house (or worse, with their partner) all weekend, then this would be ideal.

Thanks everyone! Monday to friday lets aren't popular around here, there are plenty in the city near the station and I'm 2 miles away from our station with limited public transport. He said he doesn't know anyone round here so will go to london most weekends to see family.
It's up to him to organise his life. If his living space is one room, and he doesn't want to be in it, he has to go out. I'm not being a cow saying that I don't think. He's welcome to use the garden too.

'ghastly'

Some of the appalled responses on here are really making me giggle.

YANBU sounds fine.

You have said that's the deal from the outset and so that's the way it is.

My friends whose parents had lodgers didn't have them in with the family in the evenings - it was exactly the same arrangement as you are describing.

Sounds absolutely fine to me. In fact if I were young, free and single and still city living, it's probably the sort of set up that would suit me. I lived in many such places when I first left home and I wouldn't have wanted to pop into the living room to socialise with the family. When I lived in a young persons hostel we had a communal living room and I don't remember any of the tenants using it.

I don't get why someone would think it ghastly , it's not exactly roughing it, is it.
