We stayed 3 nights in Thangka, had 2 rooms (returned to Hotel after days outside of Lhasa). We choose a quiet room on the 4th floor it was nice (the bed and pillows are real hard!). The second room was actually even better (shower door closed properly - we never touched the shower curtain). Breakfast was great - we eat a lot (egg, cereal, bread&jam, noodles, yoghurt with fruit etc), we had such a poor experience in other Tibetan hotels...
Recommended!

Wonderful hotel in tibetan style. Breakfast buffet included. The bedrooms are amazing, clean, big, well decorated, with everything you need, including oxigen bottles and medicine for hights sickness for very good prices! The location is perfect, just few steps to Jokhang and the street market. The only problem was the internet wifi absence (only inside the bar in 4 floor, free for guests). Strongly recommended!

Excellent location near the Jokang Temple, Barkor Square, markets and restaurants– central yet set back in an alley so is quiet. (We did not experience disco noises as other reviewers did). Reception service acceptable – speaks some English and quite helpful. Room is spacious with Tibetan hand crafted furniture and chair carpets.
The bathroom is nice but has no door– only partial glass partisan which does not offer privacy.
Breakfast is average with cook to order eggs and a good variety of mostly Chinese style breakfast.
No room temperature control and we had to ask the front desk to turn up the thermostat.
Free internet & safe but the safe is not bolted.

The hotel is in tibetan style, but offers all comfort one needs.

Breakfast is basic, but nice.

It's on a great location, close to the temple, market and restaurants, but also very close to a disco (well, we thought it was a disco) which starts at 10 pm and goes on until 3-4 am. So yes, bring ear plugs.
