The house was exactly as it looks in the photos, bright, clean and very comfortable. It is in a quiet but vivid area with a beautiful park right across the corner. Very close to Trastevere center by foot. We had a car for our visits to Rome so I can't estimate distance from center but I believe if you like walking everything is close (and you get to enjoy the beautiful scenery on the way!). Free parking across the apartment (plenty parking spaces but also many cars - with patience and some luck we managed to park very close to the house all 6 days we stayed!!!)
We met Bio the first day, he showed us around the house and gave us interesting tips about the area and Rome. We liked him immediately, he is nice and funny and easy to talk to (fluent in English) and very discreet as well. Overall our experience was perfect!
