We stayed in Paolo and Franziska's apartment for four days. It is located very centrally which is great for exploring Rome.
We were met for check-in by Paolo's sister Emanuela who politely showed us around the place. There is no elevator so be ready to carry your bags up three sets of stairs.
The apartment was generally quite clean and very cosy. We had all the amenities we required and were generally comfortable. There is a great little place for pizza just outside the front door. There are also heaps of places to eat nearby, and the produce market is just around the corner.
One small criticism would be that the place was a little older and more run down than it first appeared in the photos (cracks in cupboards, benchtops etc). There was a duel hose or raincloud shower, but the hot water pressure was so low the raincloud wasn't a practical option. However using the hose shower head was fine.
The apartment is a cosy little spot great for couples, and we very much enjoyed our stay.
