This apt is perfect base for exploring and experiencing historical center of Rome.
It is clean and comfortable, bigger than it appears on photos. Wifi is stable and fast. Basic kitchen appliances - just enough what you need. Beds, including sofa, very cosy for sleeping. Sewer pump in the toilet periodically makes some noise when you are using shower or flushing. It really isn't a big deal.
We used the apartment at full capacity and none of us felt any discomfort.
Overall impression of the apt is absolutely positive and somehow perfectly supplements the impression of the city itself.
All "must see" spots are within 20minutes walking distance: Colosseum, Vatican, Forum, Pantheon, Fontana di Trevi, Piazza Navona, Piazza Venezia, Piazza Campidoglio, Trastevere.
There is a mini market practically next door. Great bakeries, coffee bars and taverns in the neighborhood. Daily market at Campo di Fiori is 3mins away.
Carlo was very welcoming and gave us some useful tips on local restaurants. He responded immediately on our questions upon arrival. He was also at disposal for any assistance that we might need.
