We were welcomed by Julia, who showed us the different things we needed in the apartment. She gave us tips on how to go around Florence and even tips on where to eat. She responded promptly when we requested a few things (extra towels).
The location is fantastic -- just a short walk to the Duomo and Plaza Republica.
The place is spacious and clean and it felt safe. It would be good if the kitchen was better equipped in case guests wish to stay in and prepare a meal -- having said that, there are restaurants everywhere so there was really no need for us to use the kitchen.
One problem with this listing is that it is very noisy in the evenings and early in the morning and it echoes through the apartment. We were kept up at night and awakened in the morning by loud chatter coming from a pub nearby and awakened by busy morning traffic.
