This is a perfect base for exploring Florence! Air conditioning worked very well, which was great. The street below was a bit noisy at times, but that is because you have some good places right below you to go to!
Marco gave fantastic and much appreciated recommendations for gelato, food, places to see...and gelato. Seriously, in the course of two-and-a-half days we stopped by one of his recommended gelateria's at least 5 times...it was possibly 6. Best gelato we have ever had. A nearby place he recommended for lunch was delicious and a great deal!
The shower is a bit small, even among the other showers we have encountered in Europe. If that might make you claustrophobic, do bear that in mind, but I would absolutely stay again!
