Location is good. Hotel Eden is away from the Firenze S.M.N and Cathedral of Santa Maria del Fiore less than 10 mins walk. Mercato centrale is also near by. The staffs are very nice and helpful. The room is large and clean. The breakfast is ok, i.e. the common breakfast one may have around the hotels in Italy.
However, the WiFi access is not good. WiFi is out of function at the first day, and is slow and unstable for access in the room at the other days. Besides, Hotel Eden is just besides Via Nazionale, and it is a little bit noisy during the night.
To sum up, Hotel Eden is a good choice for my trip toward Florence, and I might stay here again next time I have chances to visit Florence.
