Tina's Home is amazing! It is very spacious so our family of 6 had plenty of space to spread out after long days of being together. The kitchen has everything you need to eat meals at the apartment, but there are plenty of places to eat very close as well.
The location is perfect if you want to explore the old Florence (it's very close to the ZTL or limited traffic zone that you can't drive in without a special permit) and the private parking spot was a stress-reliever for us since we drove. You can walk to the main squares (and the main church) all withing 15-30 minutes depending on which square (and how slow kids walk).
The apartment is also quiet! When coming home the neighbor upstairs opened his door and had house music bumping. We were a little concerned and thought we might have to ask him to turn it down in a little (at 10pm) but once we closed the apartment door, we couldn't hear it at all! If you close and latch the windows properly (which can sometimes be tricky as they are old) the outside world is hardly noticeable. We were very pleased with everything about the apartment.
Tina is a wonderful host! She has prompt communication and was on time for check-in and check-out. She has a huge, beautiful binder full (FULL) of places to do and see and even an entire section that is family/kid friendly. Parks, bounce house places, etc. She gave us a map of Florence to mark where we were and were the parking garage was (a block away) and made sure we knew where we were to meet our tours and pointed them out on the map. She is very knowledgeable about all of Florence as she is a true local! She has also laid out brochures and fliers for surrounding museums, exhibits, and activities as well as other city tourist maps. You could show up to Tina's house without any idea of what to do in Florence and find out you'd run out of time to do everything you wanted even if you stayed a week!
There is a bank with a bancomat right across the street and a little sundry shop right next door which was convenient for things like jam and milk and sodas (forgot, ran out of, and just wanted). There is also an indian place that has good food at reasonable prices that delivers nearby (we were done walking that day!).
I cannot recommend Tina and Emma's home enough! Our tours were good, but having this lovely apartment to spend the rest of our time in with such a pleasant, helpful host really made our stay in Florence the best.
