Roberto is an excellent host, always keeps in touch with you.
The apartment was clean and very cosy.
First thing you will notice it is a sense of fresh flat and cleanliness.
Another nice bonus is the terrasse, where you can enjoy the sunset with a glass of italian vine.
Roberto's advices were very helpful: best coffee you can find at Necci dal 1924.
But one small disadvantage is that the flat is very chilly.
All in all it is a great place to stay in Rome.
