The perfect place in the perfect location!!!
There were 8 of us for 3 days and then 5 of us for the next three days. This place was VERY spacious, very clean, and very close to absolutely everything that we wanted to see.
Salvatore's mom met us upon arrival (which we were late for but kept in touch with Salvatore about) after google maps introduced some complications in directions coming from the south and finding the piazza in Florence to drop our bags and guests at.
Salvatore mother is a lovely, kind woman who met us with a huge smile despite having waited for us for more than an hour and a half after our scheduled arrival time.
The apartment had everything we needed - including cooking spices and delicious oils and vinegars to accompany our meals. A grocery store is just down the road so we cooked a few meals ourselves until we discovered the sandwich shop a block away. This was a major highlight of our trip - the BEST sandwich I've ever had in my life is moments away from the front door. I recommend ignoring the boring menu and getting the truffle cream, olive paste, arugula, spicy eggplant and prosciutto - drizzled with a little bit of olive oil. The sandwich shop is called All'Antico Vinaio.
A 2 minute walk to the Ufizzi gallery and the Palazzo Vecchio, a 4 minute walk to the Duomo, 10 minutes from the Medici Chapel and 15 minutes walk to the Accademia, but in a quite corner 15 feet from the Arno - you can't find a better location. 18 minute in the other direction, you can explore Boboli gardens and go dancing at Flo - an open air bar where the locals do a little salsa dancing.
If you are looking for somewhere to stay, whether a family or a group of friends, this is it!
BTW - our group ranged from age 7 to age 68.
