Dekang Hotel is a Tibetan-family run 3 star hotel located in a quiet and exclusive area of the Lhasa Old Town. Their rooms are spacious with all modern amenities. Toilet is clean and has hot shower available.
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 roof top bar at Dekang Hotel has a wonderful view of Potala Palace.
The staff are friendly and they do offer oxygen bottles (20 RMB ) if you need it. There are many groceries stalls nearby, so water or snacks are not a problem.
On the left of 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 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.
