Dekang Hotel is a Tibetan-family run 4-star hotel located in a quiet and exclusive area of the Lhasa Old Town. It's an exquisite Tibetan style hotel. Their rooms are spacious with all modern amenities.
Dekang Hotel has a restaurant within the hotel, called Tsampa Restaurant, which serves decently good buffet breakfast in the morning. Sometimes when the occupancy rate is low, the hotel would have you order food from the kitchen.
There's a rooftop bar at Dekang Hotel has a wonderful view of Potala Palace.
The staff is friendly and they do offer oxygen bottles if you need it. There are many grocery stalls nearby, so water or snacks are not a problem.
On the left of the Dekang Hotel, there is this local food stall that sells Tibetan noodles/snacks that is always busy. The food is really cheap if you compare it with the restaurants in the old street or the hotel.
Dekang Hotel is located across the old town inside a small lane. On the map, you probably need 5-7 mins to walk to the old town, but you probably take about 10-15 mins to walk there instead, due to acclimatization.
