Would definitely recommend this hotel. I had 3 nights of very pleasant stay here. In terms of comfort, the bed is so comfortable that I am reluctant to leave the bed in the morning. The room is spacious, with a big window and dining table. It is also clean, no stains or smell at all, though the cups provided in the room could use some careful cleaning, but not a big problem overall. The design is modern, which is exactly what I wanted, after staying in old-fashioned European hotels for a week. The air-conditioner is powerful and quiet.
Regarding the location, it is about a 17-min (flat road) walk from the train station. Beware, you cannot get there by public transport, since there are not many tram and bus lines running within Florence. There are no bars or restaurants directly downstairs, which is perfect because it is quiet at night. Don’t worry though, you will find a wide range of amazing eateries within 10-15 minutes of walking distance.
Restaurants in Florence close rather late at night, like until 11pm, so you will feel safe on the way walking from the train station to the hotel at 10 or 11pm, since there are still plenty of families still dining outside.
