We spent a weekend in Florence and had a good time at Isa's place. It is amazingly central- just a few minutes from Ponte Vecchio and the gorgeous Boboli gardens and 15 minutes away from any other point of the city center like the train station, the Duomo, etc. The listing is large and comfortable for 2 to 4 people. Isa lives in the apartment right next to this listing which is perfect as you can leave your luggage with her if you arrive before the check-in time and depart after the check-out time. Isa is a wonderful host! Very friendly and accommodating and always happy out with tips and recommendations. Just a few factors that are worth keeping in mind-
1. The apartment is on the second floor of an old historic building. There are no elevators so make sure you can carry your luggage up 2 flights of stairs.
2. The windows are on the thinner side so noise carries into the flat very easily. You might be disturbed by late night revellers on the street (particularly at the weekend) and by the 6 am delivery vans. It all depends on how much sound there actually is and the noise levels you are normally used to but it is important to keep in mind that you would be living at the heart of this bustling and busy city.
3. The apartment does not come stocked with food supplies and toiletries like shampoo, tooth paste, etc. However, as I've already said Isa is very helpful and will help you acquire the necessary supplies if you don't bring your own.
In short, if you're looking for a gorgeous apartment with a lovely host that is centrally-located (opposite a lovely restaurant and near some fabulous coffee places) from which it is easy to explore Florence, I could not reccomend Isa's place more!
