The apartment is perfect to explore the city from an angle that is no as touristic as many others. The area is lively and young and you will find all you need. It's easy to get to all the main sights of the city by foot, the river is just two streets away and it will take you only about 8 minutes to arrive at Ponte Vecchio.
The room is quite big and the bed is not only huge but really comfortable. I slept pretty good. The street outside the room can be loud in the evening and at night. I recommend to bring earplugs if you have a light sleep.
You will find a really clean and well-equipped apartment. Mirco is a nice and decent guy, open and really helpful. I would have loved to hang out with him more but our schedules didn't match during my stay.
You can't do anything wrong with choosing Mirco' s place. I would definitely come back.
