We had a lovely stay in Modestino's Airbnb! The appartement is located in the city centre but in a local area. This means that Florence's top attractions like Ponte Vecchio are just a five minute walk away. There are some very good restaurants in the neighborhood, which you reach with just taking two left turns. The prices of these restaurants are very good because you aren't in a touristic area. We had take away and ate it on the steps of a church, I highly recommend. You could walk to the train station in about 20 minutes.
About the appartement. It's small, but it has everything! When we stayed in Florence it was 36 degrees outside, thankfully the appartement had air conditioning what made our stay very 'cool'. It had a kitchen with all the stuff needed, but we didn't use it because we wanted to explore Florence and its restaurants! Fun fact, in this same building Gallileo Gallilei lived for a year.
The host was very kind. We met him when we arrived at the appartement, he even carried my suitcase upstairs. He gave us a list of wonderful recommendations about what to visit, what to drink and where to eat. He's extremely fast with responding on your messages, we had some problems with the WIFI, but Modestino helped us very fast and good. The rest of our stay the WIFI was perfect. He's also very flexibel, a day before arriving and a day before leaving he will send you a message to plan checking in or out.
Thank you for your help and nice recommendations!
