Really great, the apartment is amazing and if you have come to Florence for its beauty and art it will only be enhanced by staying with Stefano.
We only stayed one night and it was so easy, Stefano made us feel very welcome. We were able to leave our bags in the apartment to explore the next day and come back and grab them before we headed off.
It is so central, just a few minutes walk from Il Duomo and if you like shopping it is surrounded by the finest designers.
Depending on what you wanted to eat/drink Stefano had recommendations.
