Sapa lies in the north west of Vietnam and is populated by myriad hill tribe minorities. It is a trekking mecca and you can reach it by overnight train from Hanoi followed by a short car ride.
The Darrah House is a wonderful bed and breakfast located just minutes from both Peddlers Village and New Hope PA. It was built in 1849 and is set on two acres of land so you definitely have some quiet and tranquility if that is what you are looking for.
