Stayed one night while hitchhiking from Songpan to Langmusi. The staff was kind and provided a cardboard for a sign.
Inside the hotel there are a bunch of plants, so you think you are in a botanical garden. Rooms are a bit smokey, but have heated beds and a bathroom.
I would not recommend it, but it was fine for a stay over night. As activity I can recommend visiting the Monastery and hike along the ridge of the grass hills, behind to a park and get down to the big square.
I had a very pleasant stay at Tangke Jiayuan Homestay during my visit to Jiuzhaigou. The location is convenient, just a short drive from the main scenic area, making it a good base for exploring the park.
The rooms are simple but clean and comfortable, with warm bedding that’s much appreciated in the cooler mountain climate. The traditional Tibetan-style décor gives the place a cozy and authentic atmosphere.
