Clementina's place is really great - it couldn't be in a better location - central to everything, yet on a small street so you don't feel out in the midst of everything. You even have your own alley across the street from the building that leads right out to the street that runs along the Arno.
The apartment itself is spacious and well-equipped - you can be there with another person and each have your own space - there's a nice kitchen, and living/dining area, and the bathroom is lovely.
Clementina met us and gave us a thorough review of the neighborhood, the building and the apartment, which was extremely helpful - was flexible with check-in time, and called us a cab to get to the train station.
Overall a really wonderful experience. The street out front can seem a bit noisy at times with windows open, but it quiets down at night and was not a bother. I would happily stay there again.
