It's our first time booking and staying in a 'minsu' and I fear that our subsequent bookings would be benchmarked against our stay in Liduo I-Think. Our choice was pretty much random (not recommended by anyone), except that it was one place that seemed to have good ratings.
The rooms were very clean, and the beddings very comfortable. We visited in late winter and to our surprise, they actually provided an electric room heater; our friends had warned us to be prepared for cold freezing nights in 'minsu' generally. Despite having provided a hot water dispenser in the general area, the room also came with a coffee machine (with pods) and a kettle, so the missus could enjoy a cuppa tea as well.
The breakfast was very good. Most of the items were top quality home-made and for those that were sourced from outside, there was a counter displaying the item brands. The view was great, right outside the window, we could see the mountains, including the icy peaks of Mt HeHuan, our target visit. The staff did a great job helping us to arrange a sun-rise visit up there.
What gets to us most was that the owner and staff placed a lot of pride in what they do and were very meticulous in providing for the guests' needs. Despite the hotel like amenities, the cold informality of your typical hotel staff was absent and we had a very comfortable and relaxing stay in I-Think.
Most folks stay 2 nights at most in Ren'ai. But our 3-night stay seemed a tad short. There's always next time :)
