The apartment was everything our hosts described it to be, and in that respect it was for us the perfect accommodation for a 3 day break in Florence. The top pros for us were:
Location- we walked everywhere the entire time we spent there. We walked from SMN train station (25 min with luggage), to attractions all around central area including the daVinci and Gallileo museums, the Duomo, multiple market areas, and restaurants, 10 min to Ponte Vechio. There's a decent grocery <5 min around the corner with fresh pastries every day.
We were only 2 so used just one of the 3 bedrooms, but the room was cozy, and the bed was very comfortable. Slept soundly every night, street is quiet overnight, virtually no vehicle traffic, double pane windows.
Apartment is very modern- kitchen is sleek with great Siemens appliances, full convection oven, about 3 different coffee making options, Smart internet TV with the owner's own Netflix account made available to us and in a comfy sitting area next to the dining area/kitchen, extremely secure- heavy door with 5 pin latching lock. Two flights of stairs to walk up, but not a huge deal for us.
Lots of lighting and receptacles, even had plug adapters if we hadn't brought our own. Excellent Samsung washing machine with clothes detergent supplied. Same goes for dishwasher.
Gian Paolo was always very responsive and accessible- communicated readily over What'sapp, email, SMS.
We were spoiled with all the extra food/cooking items they gave us- really too many to mention, from olive oil and balsamic vinegar to a big box of fruit juice, a nice bottle of Chianti which I believe other reviewers have mentioned. The only thing missing was a roast chicken warming in the oven when we arrived :)
The only con we could think of was the apartment heating was on a programmed thermostat and it would have been nice to be bumped +1-2 deg C. Again, not a massive negative, and we did have over-ride access to switch on heat mode during the programmed set-back times.
We'd be absolutely sure to stay here again on our next visit to Florence- thanks Antonella and Gian Paolo!
