I had a very nice stay at Eugenia's place!
Centrally located, yet off the noisy touristic streets (important if you care about your sleep comfort), the apartment is filled with love and has absolutely everything that you might need during your stay. If I were living in Florence, I would be able to live in Eugenia's place long term - it's just so convenient!
A note to mention - the loft bed (for the 3rd person) is nice in size but the ladder to it is quite steep - just keep this in mind when thinking about renting this flat if you are more than a couple.
Most of the central Florence is reachable by foot - and only 2 minutes to S. Croce!
Eugenia and her husband were very flexible and always available on the phone; they were constantly checking if I was doing OK and whether I ever needed anything.
And I never did! I had a full set of detailed suggestions of where to go, what to do, what to see and where to eat. Internet was working just fine. Small simple grocery to buy water was just around the corner. A welcome bottle of wine and tea set in the bedroom were very nice touches and made a difference.
