I recommend everyone to stay at Francesca's place. We had a great time in Florence. The location of the house is good. There is a direct bus n.23 to the city centre and to the train station (Santa Maria Novella) and the bus stop is very close to the house. A 90min ticket costs 1.5€ if you buy it in advance in a shop and 2.5€ if you buy it directly on the bus. In the close vicinity of the house there are great local places to have breakfast, lunch and dinner. There is also a small grocery shop right across the street which closes late in the evening. Francesca and her daughters put a lot of effort and thought into this. They have all kinds of recommendations ready for you and they even wrote them down in a short tourist guide which they created. There is a private room with a bathroom and even a small kitchen that you can use. Everything was clean. There were towels, hair dryer, soap and shampoo, small fridge, etc. at our disposal. There was even a toaster in the kitchen which we did not use. In Florence they also have city bikes which you can use if you download the app and pay around 0.8€ for 20min. You can take any bike you find in the streets and leave it anywhere you want when you don't need it anymore. There is a bike road by the river.
