Absolutely wonderful. The apartment was clean, modern, and in a fully secure building. Plus on the first floor, right past the entrance. Everything from pots and pans to clean linens was provided. I didn't have to buy anything except my food. There was even laundry soap for the washer and dryer, probably left by a prior renter. The apartment was centrally located, with a very convenient bus stop within one block. And many good restaurants as well as markets were very close for walking.
As to Enrica, she couldn't have been better. She provided lots of information about the area, and as much help as I wanted. She is a very sweet person and someone I will always consider a friend (I have actually invited her to stay with me in the US, something I don't often do.)
You won't be dissapointed if you rent this apartment. And if you do, save the cost of a taxi from the train station. Just take the "D" bus from the central station, and you will be 1 block from the apartment, a very easy walk even with luggage and only 1.20 Euros, but make sure you stamp your bus ticket on the bus.
I highly recommend this apartment. If I return to Florence, this is where I will stay. Thank-you Enrica, you are wonderful!
