I had a great stay at T.O Hotel. The staff was nice and helpful. The room was clean. The room and bathroom were small, but it was not a surprise as it matched the pictures and the room description. Even though the bathroom was small, its organisation was well thought.
The neighborhood of the hotel is not the most interesting one in Taipei, but the hotel is well situated : both Zhongshan and Shuanglian metro stations are only a five-minutes walk away, so you can easily catch the red and green lines. What's more, there is a great night market very close to the hotel.
Overall, the T.O Hotel is a good address. It really suits the needs of travelers who do not wish to spend a huge amount of money on the hotel, but who want to have more comfort and privacy than in a hostel. The service they provide for the price they ask is really good (the hotel is clean, the breakfast is included, the wi-fi is good, etc...). I would definitely recommend it !
