We stayed in Giulia and Susanna's house for 4 nights.
The house is very cozy and beautiful, it's located in a central position and linked very well with all the other places: just in few metro stops you'll get into the historical downtown.
The house owner, Giulia, will give you a complete experience making every morning a tasty breakfast, giving you useful advices about places to visit and making you feel like home.
I completely recommend this place for some Roman holiday.
