Horia's place is perfectly located for a stay in Florence. It is within easy walking distance of all local attractions, plenty of restaurants and cafes too.
I suggest the apartment is not so suitable if you are not very fit or healthy. The apartment is at the top of several flights of stairs (there is no lift, which I think is clear from the description), and the shower facilities were just adequate. You need to step into the bath to use the shower and the shower head does not reach the holder, so you need to hold the shower head yourself. (Not a major problem, but I can't remember the last time I had a shower like this. There is a shower-head holder, but it is out of reach of the cord.)
Check-in was also a little difficult as the main door was locked (we arrived at about 4.30pm so it was expected that it would be open) and the instructions to press a specific intercom button were unclear. I called Horia to see if he was on hand to help. He was not close but he said he would try to contact a friend of his who lived close by. Within 10 minutes or so we were able to get inside.
Overall we enjoyed our stay, the apartment was perfectly located and clean, but these were some issues that it would be helpful if Horia could address for future guests.
