The flat is very nice, just as we expected.
The renovation was quite a long ago, but alltogether with the furniture it created a cozy and authentic atmosphere.
There are tons of books, photos and posters on the walls, and of cource the cats. Girls loved them as the cats are very friendly (especially the grey one).
The terace was good, but we preferred to stay inside.
During our stay there was a problem with hot water, but Haydee asked a friend and he helped us quickly (he came and fixed the boiler).
For those who doesn't have WhatsApp installed on smartphone - I would suggest to install and register, because in Italia everybody uses it, and it might be useful when contacting to householders, too.
Regarding the distance from the city center: at first we thought that we would always go on foot, but actually it's quite far, so we used tram (#8) quite often (the stop is a couple of minutes walking from the house). Advantage is that the neighborhood is calm and quiet.
There's a number of supermarkets nearby, so buying food should not be a problem (one of the supermarkets is on the way to tram stop).
Definitely recommend for those looking for true italian atmosphere :)
