Fantastic location in a smaller apartment.
The apartment is located in a five minute walk from the Ponte Vecchio, Uffizi, Piazza Repubblica, and a a little longer to Santa Croce and Il Duomo. Across the street from a police station, so very secure. A minute walk away from the main drag with shopping, gelatos and plenty of trattorias and cafes. We had some heavy bags, and happy it was only 7 minute walk from the 22 or C2 bus lines, both of which run at or near Firenze SMN train station. The building's elevator can accommodate one person and a bag to go up the one flight of stairs. The windows open up to the steet below, but don't have a ny screens on them. We had a few mosquitos come in too.
There's a few downsides. Very small kitchen. The sink, stovetop, etc is literally a 3 foot wide cupboard from Ikea. Not a lot of space to cook. The shower is very tight squeeze to get in and out of and also to use for a broad shouldered American male and the hot water tank looks to be around 10 gallons. Bed is large, but two twins put together. And there is early morning & late night traffic on the cobblestone street below, which can get unnerving when the merchant's carts prattle across the stones.
Our host was very nice and welcoming. The apartment came with some basic food staples: pasta, oil, etc. Be aware though there is a cash charge to pay some sort of tourist tax that I was unaware of. This ideally should be collected through AirBNB, so bring some monies along the way.
