The host was very detailed and communicative with the instructions of the flat. It is closer to the Vatican area but it does connect via bus to Trastevere and other areas. If you want to do Rome only walking, this can be a bit far away from some landmarks (40+ min walk).
The outdoor area couldn't be used due to weather conditions (our stay was in November and it was raining) , but in summer it should be great.
Marina received us and gave us recommendations around the area. Very nice host.
