We had a very nice stay in Rolandos apartment, everything was like in the description and many reviews before.
The communication with Rolando and his son was quick, uncomplicated and very friendly, the location of the apartment just perfect in the city center.
The bathroom is indeed very narrow, which didn't bother us but could be a problem if someone needs more space. Same goes for the elevator, which you don't wanna go without to the 4th floor, but we actually liked that charming, old-fashioned thing and many apartments in Florence don't have one at all.
So we would come here again!
