Had a great stay at c-hotels diplomat in Florence recently! The staff were helpful, and the hotel is surprisingly quiet despite being in a central neighbourhood and close to the train station. There is parking in a lot right next door, though it's a bit expensive this was expected given that it's in a major city. The room was very comfortable and clean. The only major drawback was there was a faint smell of sewage in the lobby that never really went away, but both myself and my partner noted it the whole time. The hotel is located in a very central area, easy to walk to everything.
