We had a very nice stay at Marzia's flat. Yes, there is a bit of a climb up but it's worth it. The flat is just as described, big, spoltless and tastefully furnished. You can find all you need for cooking and washing and ironing your clothes.
Marzia is very helpful and kind and gave advice of what to do and where to eat.
The neighbourhood is very lively, not far from the center of Florence on foot and there are some supermarkets and baker's nearby.
We'd like to come back again.
