We stayed for 4 nights in Florence. Great location just a few minutes south of the river. Check in was easy, we met a friend of Diletta who was waiting for us.
We walked from the train station which was an enjoyable 15-20 minute walk. No need for a taxi. Apartment was fine for the stay, had all that was required to make the stay comfortable.
Supermarket opposite which has all you need if required. Lots of near by cafes and restaurants which are highly rated. Recommend the cafe on the corner.
Felt safe throughout the city and walking in the near by area of the apartment.
