Wow. A perfect renovated gem in the heart of Florence. We went in August and it was hot, hot, hot! But Karin's place was just renovated and it had 4 brand new air conditioners which kept us nice and cool.
Karin's place is modern and incredibly clean. The multiple outside decks were amazing and when you go to the top one you have a breathtaking view of the city and can see most of the big landmarks. We often watched the sunset up there with a glass of wine.
Karin is a SUPERHOST! Super fast with all her responses, met us right at the place on time, helped us with local suggestions on places to go, and even arrived a car service for us at departure.
Moreover the location of the home is incredible ... you are steps away from the Ponte Veechio bridge and it was a short walk to any of the major landmarks.
Overall fantastic place, and if you are visiting Florence in the summer (and you like AC) then you can't go wrong here!
