Been racking my brain on what to say for a bit now, all I can come up with is: AMAZING.
First of all, the place is very spacious, yet warm, stylish, and cozy. Impeccably clean, and perfectly located. We were able to leisurely walk everywhere (15 min to Duomo, 5 min to Ponte Vecchio, 20 min to Academia). The apartment is across the river from the area where the Duomo is, but this only makes it more peaceful at night for a better night's rest.
I work in hospitality and can be a little picky when it comes to these things, but Alessandra was a super host. Checkin time was a little later than our arrival and she was very accommodating, I had to travel to Chianti for a wedding and she arranged transport to and from the venue (45 minutes away!), not to mention all the town info she provided us with upon arrival and offer to be readily available if we were in need of anything. She even left little treats for us upon arrival! Little chocolate on my pillow? Yes please. Hospitality is all about details, Alessandra and Casa Mia get it.
