Alessandras place is very close to the train station (Santa Maria Novella) . we were able to easily drag our suitcase to the apartment within 10 mins. Google maps stops 100 metres before the apartment; so you need to just call and coordinate once Google maps says destination arrived.
The apartment is close to flee markets, restaurants and the starting point of the ho-ho bus point (close to the SMN train terminal). We used Florence as a mid point to go to Venice and Pisa so it worked well and the apartment catered to our requirement.
The apartment had everything we needed; just that the internet was erratic at times otherwise a good place to stay with a lift (which is a rarity).
Alesaandra was very responsive and in case we go back to Florence we would love to stay at her place.
