Stayed in Trastevere for 3 days and explored Rome. There is a good local gelato place one block away where I went twice while I was there. The neighborhood is cute and pretty quiet for the most part. From the train station the walk is about 15 minutes uphill and not too bad, but just to be aware! Rosa answered all my questions. The place does not have AC like most airbnbs in Rome. There is a sofa bed which is twin sized and 1 bed.
