Viktor's place is amazing for several reasons: it's clean, spacious, private, well located and safe. Do not hesitate to book this place if you find it available! Great value!
It is located near public transportation (tram and bus), but you will not need them as all the main attractions are in walking distance - and you definitely should experience Rome by foot!
The room is even bigger than in pictures, you'll be very comfortable no matter if you travel alone or in a group. The heat, bathroom, and shower were working perfectly - I traveled in January and was never cold. A/C is installed for warmer days.
Viktor is a great host as he is always available for whatever you may need but still keeps the space private. He gives keys to the building, the flat on the first floor and the bedroom.
