Room is no-frills but very light and airy with a big window on to the street. It's 3 floors up, which should be noted if you've got loads of bags but is no big deal if not. Florence is amazing, Guido is always available on text or email to answer questions and was a great host. The apartment has 2 rooms and a shared kitchen with full amenities, each room has it's own key. The bed we had was super-comfy, we thoroughly enjoyed our stay.
It's worth planning museum and gallery trips beforehand as there's a ticket that gives a discount if you're doing a few, which you absolutely should. Do the dome, go see David and the Uffizi Gallery, and go over the river to San Niccolo. Fab place, enjoy!
