Nicola's apartment was perfect: nicely decorated and very comfortable. I didn't have a chance to use the terrace because of the weather, but it was lovely as well. Nicola couldn't meet me in person when I checked in, but the instructions for reaching and accessing the keys to the apartment were very clear and I had no trouble at all. I did have the pleasure of meeting him in my stay and he was very kind and welcoming.
The location of the apartment is great too. It is in quiet part of the city, and only a very short walk to the Metro, so everything is within easy reach. I enjoyed checking out the local shops and restaurants -- Nicola has a fantastic guide to nearby places and other useful information. It is also close to the regional train that will get you to the Fiumincino Airport.
I highly recommend this apartment!
