I had a wonderful time at Songzhuju as a solo traveller, and I wouldn’t hesitate to stay here again. The location is unbeatable - right in the ancient city (古城) but also only a 1-2 minute walk from the edge of the ancient city, which makes things easy when transiting to other places (especially with luggage). The rooms are spotless and comfortable, with a nice courtyard, and a specialty coffee shop in the foyer.
Specifically, the service here is absolutely out of this world. Ah Fei (阿飞) from the hotel was like a local guide who helped with anything and everything. When I arrived, he sat me down, made me tea, and took the initiative to give me all his advice on how to enjoy Lijiang, with plenty of great tips, tricks, restaurant suggestions, etc. He upgraded my room to a larger one because it was available. He helped me with laundry service, organising a massage, where to go sightseeing, and how to stay healthy with the altitude. He can also organise tours and other activities (although I had already pre-booked many of my activities prior to arriving). He will add you on WeChat a few days prior to arrival - I would recommend getting in contact (WeChat has good translation features) if you want to him to help you organise your itinerary and activities. The photo is the handsome man himself.
