Thapae Gate is the heart of the old town in Chiang Mai.
It is easy to get around on foot, don't need any transportation to visit the temples, many other historical sites and museums.
There are plenty of restaurants and bars around, the pub street is only in a 5 minutes walk.
The Night Bazaar by the river is in 10 minutes walking distance and the most famous Sunday Walking Street is just on the corner. :)
There is a Muay Thai boxing stadium nearby - we can get discounted tickets for the show.
