Location was not posh, but I was in no time feeling unsecure - even at 21:00. People just ignored me but helped if I asked for directions. Not many speak English so it is recommended to know a bit of Italian.
The place is very near the train station and metro - very useful. The studio had everything I needed and even more and everything worked OK. The bathroom is great. The host had put some food for my use and asked whether I needed help with transfer. There are good shops to buy food nearby. Not noisy and I could keep the window open for fresh air.
