The Termini station is about 10-15 minutes by walk and main sites are around 30 mins by walk. Rosanna is really nice and helpful, we arrived quite late and she was waiting for us with nice Italian cake (which was a pleasant surprise) :). The bed is comfy and big enough. Saturday the locals are pretty loud, so if you think you are going to sleep, forget it :D but this is what you would expect on a Saturday. You definitely need to go to bakery around the corner, which is cheap as chips and really tasty (they even have vegan food too). A few streets away there's a coffee house, which has great croissants (try the chocolate one) and coffee. And I think one of the biggest bonuses is the massage chair Rosanna has. After a long walk it was quite refreshing.
