The stay at Viktors place was perfect!
Viktor is a really humble guy, who is very helpful and always up for a quick chat. I felt very welcomed and quickly discovered the area around, which is just amazing. You have Campo de' fiori with a market (I think everyday?!) right in front of your door if your door and Piazza Navona in 3 minutes walking with its amazing gloomy atmosphere in the evening. Also the Tevere, Torre Argentina and many other spots are close by. In that sense:
Dankeschön und bis bald :-)
