How about the Firenze Campo marte station ?
Closer to my hotel ? That is the station that are train from Cinque terre is coming to ..

Budget Car Rental in Chiusi. The office is a very short walk down the street from the train station, and it's easy to get to Tuscany locations from there.

Grazie fellow traveler

Chiusi is not anywhere near Florence or your lodging

You are closer to Rifredi station

Why did you book a train to Campo Marte?

I can get a faster train from Cinque terre to that Campo Marte station for some reason.
I think I messed up with my hotel location.
It's not very close to the train stations.
I was thinking I can just get a train to the closest station to my hotel which I think may be Firenze Statuto. ?

Where are you coming from?

“Cinque Terre” is an area not a town or a station

Can your hotel be changed? It’s really not a good location

If you arrive at Campo di Marte it is probably because you are taking the fast FrecciaBianca from La Spezia, which calls at Campo di Marte and not Santa Maria Novella. That is fine since it's the fastest way to come from the Cinque Terre, but the best solution from the CM station to via Cironi is a taxi. You could potentially go to the Ridolfi stadium by taking the aerial walkway from the Campo di Marte station across the tracks and then take the no. 20 bus, which goes near your apartment, but I imagine you'll have luggage, so a taxi is more convenient and faster.

The rental cars are all on Borgo Ognissanti (just south of the SMN station) except for Hertz, which is now on Via Alamanni and the west side of the SMN station. It's too far to walk from where you are staying, especially if you have luggage, therefore a taxi is the best solution.

I presume you are staying at the Affittacamere Anna on 37 via Cironi because of the low price, but it's not a convenient location. I also wouldn't want to be so close to the railway. I lived near the railway as a small kid in Florence, and it can be noisy even at night when those trains whistle and wheels make noises on the tracks. I hope you are not a light sleeper.
