Translation of Sitzbank

I try to learn English as much as possible so that I can travel next year to the United States. I would agree to your proposal but I also need to find good teachers. My goal is quality and speed.
Sorry, I did not know that I have a meeting with a friend. I will talk about our trip. Many thanks for the email and I hope we write eachother again soon and next time longer letters, I promise.
There are great museums if you like art. The most important is the Van Gogh museum. There are good restaurants and bars in the center, it is very international. I hope we can stay in touch.
