I haven't actually met my host, since she was working when we came and when we left. She was very good in organising things by mail and her husband showed us the place and gave us the keys, he was also the one who checked if we left the house in a good state.
We have stayed in the house for a week, so have seen all days in this neighbourhood. On friday and sunday there was a party at the bar next door, which made sleeping in the living room (the sofa bed) less comfortable. If you want to hang out in bars as well this is great of course, since the neighbourhood is very lively and lots to do around the corner. Wifi is fast and reliable. In general we had a great stay and especially enjoyed the restaurant 50 meters to our right. Very good pizza for a very good price and cheap beers.
Transport to the city centre is pretty easy, you can take tram 5 or 14 to/from Termini and bus 105 and 81 go to several other places in the city centre. Very busy lines though, so watch your wallet and other loose valuables.
