I highly recommend Serena's lovely apartment in Rome, overlooking the Vatican walls! The room I stayed in was easily suitable for 1 or 2 guests - everything included (including a TV in the room); the bed was comfortable; the space was private and quiet; coffee and sweet pie on arrival; and the location is perfect (central but not directly in the heart of the hustle and bustle of Rome city centre, and direct view of the queue for the Vatican museum so you can plan your visit...)
I stayed one night, and Serena's sister kindly waited for me to arrive (my train was late and the poor thing had a tooth ache, so I was very grateful for her attentiveness to guests)
Serena was also kind enough to provide a late checkout the next day so that I had time explore Rome before moving on to my scheduled tour of Italy.
Bathroom facilities were great (especially compared to hotel facilities in Italy...) and the kitchen is fully equipped so if you had a longer stay it would be an added benefit.
Free wifi is included, however I couldn't work out the password... Serena was available at night by phone to try and figure out what I was doing wrong, but I couldn't get it.
A kind and friendly introduction to Rome, I would stay again if I am lucky enough to have the opportunity.
