Su's apartment is very nicely and modernly furnished, it's clean and very close to the train station. It's only one stop away from Florence central station and the train leaves every ten minutes or so. Also very nice is the private parking lot so you don't have to worry about parking in the city and the parking costs.
Last but not least, Su's husband has a great restaurant in the city centre! We went to eat there twice and it was delicious. The restaurant has a big pizza oven and even though it's in the city centre, it isn't as touristic as some other restaurants, great food for a great price, which is a big plus.
