Lucia's place is located just next to Termini station and it is in walking distance from almost all main attractions in Rome.
We had zero trouble in communicating in italo-english with Lucia, who's very lovely and kind lady. She was kind enough to give us some advices and recommendations.
The place itself is basic, but offers everything you need for a pleasant stay - wifi, private bathroom, tv, and even a small refrigerator.
So we would definitely recommend Lucia's place if you're looking for a good budget solution in Rome.
p.s.
Be ready to pay the city tourist tax on arrival - it is 3.50EUR per person per day.
