Roberta's apartment is beautiful and perfect for a couple or 3/4 friends. The kitchen area is really nice to have breakfast in the mornings and relax before you head out. The location is great as its in a lovely neighbourhood that is a 10 minute walk from the centre of Florence.
I really enjoyed the walk away from the tourist area back to the quite location of the apartment. There is a lovely gelato shop and a few restaurants around the apartment and if your feeling very lazy there is a pizza shop next door. There's also bus stops right outside the door that take you into town and up to piazza Michaelangelo for €2 (beautiful lookout overlooking Florence)
We never met Roberta throughout the duration of our stay but when we arrived we were greeted by a lovely lady (Patrizia) who gave us the keys to the apartment. You have to pay tourist tax which is €2.50 per person per night and as we arrived at 10pm we had to pay €20 for a late check in. Personally I find this fee a bit ridiculous as we booked the apartment for that whole day and only arrived that night to stay in it. I think the fee of renting the apartment should be enough.
Overall I would recommend this place if you want your own space and to be left to yourselves.
The power did cut out at one stage (there's a fuse box in the cupboard but another one just outside the apartment door on the wall). The switch had tripped and it was the one outside the apartment so this is good to know incase it happens again.
