We were in Florence for 3 days to be exact. First of all, let me tell you Andrea was an exceptional host. He was waiting for us at the train station to receive us on the day of our arrival. He even took some of our luggage and help us. Though we couldn't walk the distance to his home due to the enormous amount of luggage we had, so we took a taxi along with him. When we reached his apartment, he had a basket of fresh lettuce and salad leave grown in his own garden for us on the dining table. He was also very kind to keep a water bottle for us cold is required by us. The house was as we had expected and it was in a nice locality. Every thing was at a walking distance of say 10 to 15 mins, could be lesser if you did a brisk walk. My mothers age prevented us from walking very briskly so it took the said amount of time. There are good eateries around the house and super markets as well. Florence is so small that we covered all the attractions by foot. We didn't have to use the public transport at all. The Duomo is 10 mins walking. If you reach the Duomo which is literally the center of Florence, everything from there is just 5 to 8 mins easy walk. Though after a long days sightseeing and walking, the walk back home seemed a bit tiring, and it being Florence, no metro or proper bus service as well,since the old and sightseeing part of Florence is not serviced by buses at all, and if it is, very less. So you're better off walking.
The house was at a good location and at a safe location as well. No safety problems so such sorts. Though 1 bathroom for 4 people seemed a bit less for us, but we were geared up for it when we had booked it and it wasn't such a big problem as well.
All in all our trip to Florence was great. We visited Pisa as well from there which is a 1 hour journey from SMN firenze station. Our trip was excellent all thanks to Andrea's hospitality and kindness.
Its a great house, with the basic amenities available to you and all times. There is a bit of a problem relating to the Cell service. At all times we had no signal inside the house, so our only savior was the WIFI, but at times that was also behaving weirdly, maybe there were some problems during that day.
All in all great trip, great host, great city & history. Would recommend it to people for stay.
