This Airbnb is best for young people that want to experience nightlife. My wife and I stayed in the "Heart of Florence" room, which was uniquely decorated. It is very large, and has a shared bathroom close by. The apartment is a 700 meter walk from the train station, and it is very easy to find. It really is within walking distance to every sight in the city. Frederico is very kind, and allows you to use his kitchen and wifi, which are both decent. The espresso was wonderful, and it helps the budget when you can make your own coffee in the morning.
Unfortunately, this room has some problems - it is directly above a storage unit owned by street vendors, and they are opening and closing a LOUD metal garage door at all times of the morning/day/night. It also has no insulation, so you can hear everything outside the window. Cars, bikes, people talking, construction, whatever. You can't sleep well. Also, there is a glass block window from the bathroom into the bedroom, and when another guest turns the bathroom light on, it illuminates the whole room. I ended up hanging a towel over the window, so I wouldn't wake up. Frederico provides ear plugs, but it wasn't enough - my wife and I got no sleep the three nights we stayed. Also, this is a old apartment - like 300+ years old. It is musty, and cramped, and a bachelor's pad. Not a romantic getaway. My final opinion? The apartment is great, the room is not. If you can, stay in another of Frederico's rooms- they are less expensive and quieter, and you get all the benefits of his home.
