Very close to Firenze SMN train stations. Difficult to find because Florence has two kinds of house numbers (red and blue), so there was a bit of confusion upon arrival.
Cute and comfortable space. Apartment is at the top of the stairs (about 45 steps), no elevators, so be prepared and plan ahead with luggage. There's also a really small front door to the building (half of a normal door width). There is also a pub right below the windows so there is noise but it wasn't very bothersome to us - the hosts have earplugs provided too if you need. But a lot of people smoke at the pub, so the smell will travel up to the apartment regardless of whether or not the windows are closed.
Beware of the shower - it is extremely slippery and the mat keeps sliding around on the shower floor!
Also near many amazing restaurants (TiraBarella was our favorite!).
