Mariam is a warm host, who is also blessed to have a lovely and convenient place for her guests -- close to the train station (but not noisy at all), and 15 minutes walk away from the city (for that residential feel). The room you get will take 3 flights of stairs to get to once you enter the building (and another small set inside), but it's completely worth it for how roomy it is AND that balcony. I was blessed to have good weather during my short stay, and kept saying "good morning, Florence" to the sounds of the bells nearby. Breakfast is arranged in the morning (and sometimes she offers dinners!). She gives good recommendations on where to eat and how to get to specific spots in Florence.
Thank you for a pleasant stay!
