Isabella was very helpful in getting us settled into Florence. She wasn't in town when we visited but she had her friend meet us and she was extremely friendly and welcoming.
The apartment is a great size for a couple and has everything you could need, except wifi. It was a bit of a pain having to go find wifi when trying to connect with friends/family and plan future parts of the trip, but there are a few cafés/bars in the immediate area that you can go to and get free wifi.
The apartment is in a great location, only 5 minutes but the train station and has a great feel to it. It's very clean, bright, spacious, with a fully equipped kitchen and has a nice view of the sunset over the distant hills. The washing machine was another plus! Overall, we had a great stay.
