We stayed in Chiara's place for over 3 weeks and loved staying there. The location is fabulous, as you can walk throughout the historical centre of Rome. It's a narrow street, without cars, therefore it's very peaceful, no noise at all. The apartment has everything one needs in terms of linen, kitchen appliances etc.
We stayed in December/January, and the apartment was extremely well heated.
Chiara was an excellent host, and responded immediately to any query.
