We had a great stay at Geralds place and strongly recommend to visit. It's fairly easy to get to the apartment both with a bus and possibly even on foot (although it's going to take you about 30-40 minutes from Termini if you are willing to walk. Gerald provides good local information about the neighborhood in which you will be living and suggests some great places to visit. The only downside is that it might be a little loud outside, given that the homestead is located nearby a tram stop, not to mention the ambulances, they run down the street like crazy! Anyway, besides some sounds, it's a great place to stay. Pigneto is a nice neighborhood, so on the downtime from exploring the central and the "main attractions", you will be genuinely surprised while exploring it.
