Washington, D.C. travel tips
The Georgetown area was created in the middle of the 18th century and is considered the oldest place in the city. It is a prestigious and expensive area. The streets of Georgetown are full of expensive shops and old mansions. Many young people can be found on the streets, as the university with the same name is located here.
If you are travelling to Washington, one of the budget accommodation options is to live in the nearby town of Arlington and get to downtown Washington in 15-20 minutes by metro. Housing prices there are almost twice as low as in Washington.
There are not many good coffee shops in Washington DC because the locals prefer tea as a tribute to the English past. However, tea is often drunk here cold, with ice, lemon, or milk, and without sugar.
