Great apartment that could comfortably fit 4 people. Lots of natural light and high ceilings. There is a small kitchen that is full stocked. Internet was excellent, as I worked there for 4 days and did not have a single issue. In terms of walkability- slightly north of the city, with a ~12min walk to all of the main tourist attractions (Duomo, David, etc). About a ~25min walk to the other side of the river.
Highly recommend, and a really good value for money!
