What are transportation options and challenges in Florence, Tuscany?

Anyone who lives in my city must know that the prices of Florentine houses are very high both for rent and for purchase. Florence in summer is one of the hottest cities in Italy so I would consider buying good air conditioning especially if you live on the highest floors of buildings. if you decide to buy a house in the city center finding parking for your car is a real challenge, especially if you have large cars and if you live in a family. Leaving aside the fact that many of the streets in the center of Florence are exclusively reserved for pedestrians so unless you drive a taxi, you better go by other secondary roads (in the main hours of the day).
