We absolutely fell in love with the zen b&b - and especially Kokoro the dog. The place has an entrance through a lovely zen studio which leads to a secluded oasis in the heart of trastevere., replete with zen garden style landscaping and a water feature. The place itself is cozy for a couple and is done in a Japanese style, so not your typical US layout. If you are in Rome for a few days, trastevere and the Jewish grotto are very interesting to check out. If you're just site seeing, the #8 tram will take you everywhere. Also highly recommended are the restaurants close by to fit all budgets (AnnaMaria has a fantastic list for you) - we ended up going to L'Essenziale thrice. It's important to note they have a few pets - we loved it though.
