Nothing more to add than what other people have said.
Great location/neighbourhood, great views from the apartment, close enough to all the major sights in this beautiful city.
The steep staircase didn't really present any problems for my 72 year old legs - each of us with rucksacks, but we do a lot of hiking!
I know that mosquitoes are a problem in Florence.
Despite taking all precautions - closing all windows, blocking the chimney, convinced that we'd killed the few that were hiding from us, we were nevertheless woken during the early hours by the tell-tale sound of one or. two rogue ones, their wings beating in our ears - not a big problem, just cover up!
Just intrigued to know how they get into the apartment!
Advice - take some mosquito repellent with you.
