We spent 3 nights in Giorgio's apt. It is right near trevi fountain but the apt itself is very quite and lovely. All attractions are quite nearby. . Giorgios staff were super helpful and professional. Giorgio arranged for airport transfer as well as private tours of Rome. As I mentioned to Giorgio, one of the guide was ok, and the other one was excellent.
As others have pointed the Apt has one bathroom which is not ideal, but we knew about this.
