My mother and I spent two days at Marco and Cristiana's and had a lovely time. Cristiana greeted us and spent time going over the map of Florence, giving us recommendations on how to make the most efficient use of our time so we could see all this great city had to offer. Their apartment is 5 min from the train station which makes getting to and from very easy. We stayed in the larger bedroom which worked great for two people. There is a shared bathroom with other guests but the bathroom time was never an issue for us and we enjoyed meeting that person as well. Do yourself a favor a leave some time in the morning to sit and have breakfast with them. It such a nice thing they do for their guests and it was something my mother and I really enjoyed. If you are looking for a great place to stay while in Florence, I highly recommend staying here. My only regret is that we only stayed 2 days.
