Dear Sir

I’m interested in the furnished (备有家具的)house near Dedham which you made known in yesterday’s paper, for my husband and I are coming to England in June and need accommodation(住所)for three months. Would you please tell me exactly where it is and give me details (细目)of bus and train services in the area ?We need a house on a busy street. And I would also like to know about the local(当地的)shops. Do the local shops still supply? I know they did ten years ago. 

I would be thankful also if you would tell me whether you supply sheets etc, and whether a laundry(洗衣房)calls at the house. The rent (房租)you ask sounds reasonable for the size of the house. How do you like it paid? Weekly, monthly or in advance (提前)?

I would be thankful for an early reply.

Yours

Pamda Smith
