Marie-Claire was a great host who was very responsive. We had a slight issue with the toilet when we first arrived but she was quick to fix that within a few hours of our arrival. The apartment located very close to many of the major tourist points in Florence and as many others have mentioned it is a short walk from the train station. The only thing I would caution people is the apartment is immediately located near many non-Italian restaurants and corner stores so if you are looking for an experience of living within the locals this might not be the best choice for you.
