You stay in a nice room on the second (third for Americans accustomed to calling a lobby the first floor and not floor zero) floor that had all the accommodations you’d need. The keys are a little tricky to use and the door to your room doesn’t actually shut unless you lock it, which are all little quirks that once you’ve figured out are not a problem again.
As for the location, Florence is small enough that not being “in the middle of the city” isn’t a problem, the walk to the Duomo was about 10 minutes and you see the rest of the city along the way. There are some “snack bars” and restaurants in the area.
