I can only recommend booking Stefano and Melanias appartement. The appartement is a 5 minutes walking distance away from the vatican and with Public Transport you're quick around the city to check on all the major touristic sites. There is a lot of restaurants and bars/cafés in the area as well.
The communication was fantastic, responses to text or phone came almost instantly. The Check-in and -out was really easy and Melania gave me some tips what to look for in Rome.
All around a great expirience from my part.
Thank you Stefano and Melania!
