The place is just great!
For me, it was perfectly located, far of the crowd and close to the authentic Italian restaurants and bars. Also very close to the subway station.
The place is decorated neatly and it made us feel like home. It was so great to come back to the apartment after a exhausting day of exploring and having a relaxing time there. We had everything we needed there.
Nicola was a great host: quickly responsive, comprehensive, and instructive. The recommendations we had were great (specially the restaurant Sora Rosa and the pub Hopificio). The place is also close to supermarkets and other amenities.
The value was also great, our best one in Italy. 100% recommended. I'd stay there again if I have the chance :)
