My girlfriend and I stayed 1 night at Valeria's place and can HIGHLY RECOMMEND it! Communication with her was very easy also beforehand, as she quickly answers to your messages and questions! The place is very close to the train station and at the same time in the absolutely BEST neighbourhood of Florence: beautiful and quiet - no tourists around ! ; )
There is a bike rental in the same street but you can also walk to the city - the old bridge, Palazzo Pitti and Boboli Gardens are just around the corner!!
Valeria prepared a nice guide (recommending bars, restaurants) and maps of the city. Breakfast was great and Valeria very help- and joyful, answering all our many questions about the town and getting also into nice conversations! We felt very much at home at her BEAUTIFUL(!!) appartment and actually did not want to leave!!! So, this is indeed a FULL RECOMMENDATION of her place! Go and see yourself!!
