I wasn't on the trip, just helping my friend to make the booking. This is their feedback on their stay.
It is located at 4th floor and the apartment is very nice, modern and clean. It is situated in the heart of florence and it is just 5 minutes walk to the train station. It is surrounded by restaurants, bars and supermarket. It has 2 rooms with 2 bathrooms. Balcony next to the upper room , a very unique design. A great place to stay.
