My boyfriend and I stayed here for a week - it was clean and had everything we needed. Valentina's parents met us as we stepped off the tram and showed us to the apartment round the corner. They left us a bottle of wine which was lovely and there was coffee, tea and some food. There's a decent sized comfortable bed (my boyfriend is about 6'5" and it suited him!) though it does get hot upstairs in the bedroom. It is nearby a road so it can be noisy at night if you're used to silence. However, it is close to the tram stop that goes to Florence station and near all the big attractions. It is a convenient location for getting out and about. Good shower and a hairdryer.
Some tips: The pasticceria next door seems to be closed down but we found one opposite, over the tram line, that was open at night so you could get pastries for the next morning.
There is a good grocery shop called Pam round the corner that has anything else you need.
There are two photobooths (fotoautomat) outside Florence station near the tram which are fun and give nice photos but no warning when it will take pictures!
One of our favourite meals on our trip was at Trattoria Sabatino - simple traditional food, good prices and delicious!
