Casa di Nina used to be the home of a middle class family: very
decorous, large rooms, well made doors and details...It's a very
nice house, There are two very large double bedroom, a small single
bedroom (with a window, anyway), a large bathroom, a good, full
equipped kitchen and a pleasant balcony all around.
As well the zone is very good:
Casa di Nina is at via Casilina 109, that means at border
between "Pigneto" and "San Giovanni" quarter. Pigneto is a very
popular part of Rome, where you can meet an old lady sitting in
front of her house, a traditional market full of colours etc and -
from a few years- it become "the Village" in Rome.If you had seen
some italian movies made in fiftys, as "Roma citta aperta" by
Rossellini or several Pasolini's movies,or some parts of
famous "ladri di biciclette" OK that's the part of Rome they have
been filmed.
San Giovanni is a middle class quarter, built at beginning of XX
century, with a lot of good shops and very dressed
people.
The zone is very safe and there are not too many tourists around so
that, after enjoying Roma's beauties you'll have a dinner or an ice
cream with roman people (I think you don't travell to meet only
americans, do you?)
The closest important attraction is Basilica di S. Giovanni you can
reach with a 10 minutes walk. At few minutes by bus or by Metro
you'll find Colosseo and all the beautifull rest of Rome
