I stayed for 2 nights.
Although it's cheap, I would not stay there again because;
1) Rooms are old, not cleaned with enough care(not horrible but neither good)
2) Breakfast Buffet is simply lie. Instead, they give you a small box filled with cheap bread. No coffee and no actual food like you expect for Taiwan.
3) It's literally in middle of nowhere. Taichung has many great Night Markets, restaurants, and shops. However, non of them are near to this hotel.
Still, it is the cheapest hotel I found in the town for twin rooms. If you want to have your own room to stay rather than a shared guest house, it might be a choice. However, if you want to enjoy your stay, I would definitely recommend to stay in a better hotel in a better area of town to enjoy walking wonderful parts of Taichung on your foot.
