Hello Y/N,
I haven't see you in a while. I have read your email and I'm really happy that you will stay in my apartment for a day! We're bestfriends for years and now we can finally have a sleepover!
My apartment is in the centre of the city. It's light blue and it's really high. It has 20 floors and my aparment is in the 6 floor, in the end of the hall. The building is really crowded outside, so I will wait for you at the gate.
My apartment is very modern, so you can only pack your clothes and some snacks, we don't need much. You will see tommorow. But it only has 1 bedroom so you have to sleep with me in a room. But that's okay, I have an extra bed!
See you soon,
