The location of this appartment is ideal - you can easily walk everywhere and even visit the house during the day (inbetween different "activities"). There is a lot of restaurants and some food stores near the house.
I found it easy to find the appartment since the location is easy to reach and Mauro gave clear instructions on which doorbell to ring etc. If you have huge luggage or difficulty with moving, keep in mind that the stairs can be a little tricky. There isn't a lot of them, but they are quite steep. Mauro offered to help me even though I only had small luggage.
The appartment was clean and peaceful. I heard some noices from the street to my room but it didn't really bother my sleep or anything.
I could have used the kitchen but I used it only to store a few objects in the fridge and borrowed a glass.
Mauro is a friendly host. He gave me some tips and I bet he would tell even more about Firenze if you asked.
I would definitely recommend this accommodation to anyone visiting Firenze :)
