We stayed here for 3 nights in September 2017 and it was perfect! Trastevere is a great area, close to all the tourist attractions but with more character. Mario's apartment was perfect and he was very easy to communicate with and very responsive. My only suggestion would be a video of how to walk to the apartment from the main road; there are a lot of streets in Trastevere and it can be confusing to find your way. Overall, great location and value and fantastic host! Highly recommended!
