If you are staying in Florence and Marco and Cristiana's place is available, stay here!! Can not recommend it more. They are amazing people and truly love their city.
Cristiana sat me down on the first day and showed me every place I needed to see with timing suggestions, where to eat (where the locals eat), what to do etc. They also provided an amazing breakfast every morning. Was great to sit down and chat with Cristiana over breakfast and the 3 of us also had great chats over wine and cheese which I brought back from my walks and cracked open together.
The location is away from the touristy bustle but Florence is so small it's so close to walk everywhere. Such a good location and near the bridges too.
The room was amazing! So comfy, with a lot of personable space and lockable.
Stay here, you won't regret it.
