Elly was a very nice host and communication with her (whatsapp) was very easy. Whenever something came up (flat related or just any question), we could ping her and things were solved very quickly. She gave us some great tips for restaurants, showed us on a map where the next supermarkets are and so on. She also gave us an extra table to put on the patio (we love eating outside and didn't want to do it with the plate on our laps).
The flat itself is very nice, we especially loved the patio to enjoy the morning coffee, lunches in the sun or a glass of wine before dinner. :-) It is also well located, pretty much everything in Florence is reachable from there within 20 mins by foot.
Good things to know about the flat that you can't see from the pictures:
1.) The doors to the patio have mosquito nets! Idiot me found out about it only after three weeks in the flat, struggling with sleep due to the constant buzzing of the mosquitos. No need for that, just lower the nets (one of them is also accessible from the outside, so when you sit in the patio, you can still keep the nets closed).
2.) Internet is really great there. We were a bit worried as we had to work in home-office from there, but everything went very well, the wifi connection was very strong and we had no issues working on our remote desktops back home.
Two little warnings for those who may book the flat for its "gym" or who struggle with back pain:
1.) The mattress of the bed- despite being fairly new and in good conditions- is VERY soft. For us, struggling with back pain, it was not always easy to sleep there. The sleeping couch in the living room (which has some sort of a built in bed) however is super comfy and as the windows go to the patio, it is also very calm. This just as something on the 'good-to-know' list.
2.) The 'gym' is a windowless room in a rather moist basement.... we didn't book the flat for the gym (the reviews that we read on airbnb were quite clear that it's not really usable, so we didn't have high expectations) and just used it for storing our suitcases. Be that as it may, the flat is very close to the river Arno, which is great for jogging! If you turn east you quickly can leave the streets and cars and just walk/run by the river.
We had a really good time there and I'd book the flat again. :-)
