Sav is one of best hosts I've had. Notably, he gives a good map and guide of Firenze, things to do, restaurants to visit. Whenever I had any questions, he always responded asap.
The apartment is clean and warm (considering I came during winter!), I felt comfortable upon check-in. It was also easy to find plus there is an elevator. The location is great as well considering there are a few restaurants/grocery stores within walking distance, or the option to take a bus or the tram into central city.
