Mario & Domenico's guest-house has a perfect location.
It is just a few bus stop or 20 minutes walk from Firenze SMN stations.
Firenze SMN is located exactly in the historical city centre.
And you can get the bus/trains in Firenze SMN to visit nearby tourist sites.
For example, Pisa, Siena, the Mall outlet etc.
Supermarket is just near the guest-house as well.

The room is clean, tidy and with a terrace.

The guest-house provide everything you need.
For example, a well-equipped kitchen, good Wifi, TV etc.

Mario & Domenico is nice and helpful host.
They always reply message quickly.
They also provide useful travel information if you want.

I highly recommend here.
