We had a lovely 5 night stay in Gian's apartment, which is in an excellent location to walk to from the train station (we arrived and departed from here but also used the train to visit Pisa). It was also easy walking distance to the main sights and La Cascine park and pool (worth a visit if you need a rest!). There are some good restaurants and gelaterias nearby which are fortunately less touristy, plus a small supermarket.
The apartment had everything we needed and more, including spare pillows, iron and ironing board, cleaning products for doing washing etc. We used the washing machine once and our clothes dried quickly on the airing rack. The furnishings and finish were great for us and it felt very spacious for a studio.
The only minor points for improvement were that the bathroom didn't air so well as there is no extractor fan and the air conditioning had to work quite hard to cool down such a large space.
We would definitely stay here again when we return to Florence and would recommend it to family and friends, as it was excellent value for money and a lovely space to stay in.
