Wow, what can I say about such a wonderful experience? By far the best place I have stayed off Airbnb (and I've visited some pretty good ones!). The apartment was absolutely lovely, clean, had everything we needed, and was big (2 bedrooms and 2 bathrooms and also had the opportunity to do laundry). Not to mention a little garden patio area out back. It was about 30-40 minutes walking to the Vatican but less than 5 minutes to a red line metro stop (which hits most of the main tourist attractions).
Nicolo was a great host, wonderful at communicating. We arrived early and he stored our bags and bought us a coffee. He gave great recommendations on transportation and where to eat - we never had a bad meal the entire trip! He also arranged for us to get to the airport via driver and when there were transportation strikes, drove us there himself.
I would highly recommend this apartment to anyone considering a trip to Rome!
