Marc's apartment is outstanding! The location is excellent and is only a few streets away from Santa Maria del Fiore and a 10 minute walk to Accademia Gallery and 20 min walk to the central station.
The Medieval decor and furniture ad a unique charm to the place which is equipped with a modern kitchen and bathroom and comfortable bed. The whole flat is full of thoughtful details from the amazing decor and the complimentary wine to pocket guides and really valuable art catalogues which I found to be great references for planning our visits to Pitti Palace and Uffizi.
Communication with Marc was excellent and he made sure that we feel comfortable in the flat once we checked in.
I wouldn't stay anywhere else next time I am back in Florence!
