Dear Sarah,
I hope you have been settling into your new job well! I am getting in touch because I have some exciting news: my flatmate has just moved out, and I immediately thought of you. I would love for you to move into the spare room here.
The room is a bright, quiet space at the back of the apartment, and it comes fully furnished with a comfortable desk and plenty of shelving. Our flat is quite spacious, with a large open-plan kitchen and a balcony that gets great afternoon sun. It is located just a ten-minute walk from the metro, so commuting will be a breeze for you.
I think this would be a fantastic arrangement for both of us. We have always had such a laugh together, and it would be wonderful to have some company again. Plus, since you are currently looking for a place, it would save you the stress of dealing with agencies and high deposits.
Let me know if you would like to come over this weekend to see the place. I would be thrilled to have you as a flatmate!
Best wishes,
Mark
