Great apartment, 5 min walk from Santa Maria Novella train station. All main sights in Florence were easily walkable from here with the bus station right outside on the corner. Gaia was very responsive, let us check in early and was very helpful throughout our stay. Highly recommend this unit. Only thing to note is as advertised it is on the 4th floor - there are exactly 99 steps to get to the apartment which can be a little difficult if you have heavy bags or after long days of walking!
