The apartment is in a great location for exploring Florence and a 5 minute walk to the Duomo, to the main train station and to San Lorenzo markets. This great location also means that there is a lot of noise throughout the night. As others have noted, bring a decent set of foam earplugs.
The apartment itself is large and spacious and Sharika was a great host, promptly replying to our emails and helping fix the minor WiFi/Internet issues we had.
The only down side to our stay was that the bed is in desperate need of a new mattress.
Although our stay was in winter, the apartment has air conditioning which would be a must have in summer!
