I highly recommend Lucas's B&B for a great stay in Rome. It is located near Termini station, so it is easy to get to after a long train ride or from the airport. The setup at Luca's is excellent. The main entryway opens to a small hallway, where the doors to the bedrooms are. Lucas's living space is separate, so you don't need to walk through it to get to your room. My room had its own bathroom, so it basically felt like a little hotel instead of camping in somebody's apartment. It also had air conditioning which you can control with a remote, which was a huge benefit during the hot summer nights. It is about a 5-7 minute walk to the subway, and there is a tram that stops outside, but I never used it. The wifi was working well also.

Luca greeted me when I arrived and was very friendly and helpful, giving me recommendations for nearby restaurants and a map. I was out and about for my much of my five day stay, but he made a point of checking in on me halfway through to make us everything was OK. All in all, a great stay and a great host.
