I would highly recommend Laura' place! It is clean with all amenities one needs! Its 10 min walk from Roma Termini and also has a supermarket around the corner. The Colosseum too is at 20 min walk! The rooms are spacious and the private bathroom really makes life easy!
It was very easy to communicate with her and the check in was smooth. Laura's father stays here and he is most definitely a super host! He showed us around the house explaining everything and also gave us a map and marked all places that we can visit. He was also kind enough to let us use the kitchen and cutlery. He is always very cheerful and the place always has a happy vibe about it!
