Stefano's appartment is really well located, in a very central area (2min walk from Piazza Navone, bars, restaurants, buses... at the heart of Rome historic and social centre).
The apartment in itself is quite small and the kitchen and bathroom are really tiny, but the terrasse is huge. It's a perfect place if you come in Spring/August.
Stefano was a careful and communicative host; we had minor troubles with AC and the keys, and he helped to fix everything quickly. Check in and check out were well managed.
