You want to invite your english friend to your town for a few days.write an email of 50-80 words in which you: invite your friend to stay at your house; suggest possible dates for the trip; suggest activities you can do together when your friend arrives.
I would like to invite you over for a few days. You can stay at my house, I will be happy to have you as a guest. We will break up for long summer holidays in June so you can come over in June of July. When you arrive we can go camping, sightseeing or just go to local restaurants and visit theatres so you can experience our culture and food.
Looking forward to seeing you,
Max
