The house in San Lorenzo was according the description and was very adequate. The location in Via Tiburtina, very close to La Sapienza, 15 min to Termini and 30 min walking to Colosseo was very convenient to me. The neighbourhood is full of students and very lively and it maight be a bit noisy during weekend but it is worth living there. The only problem on the house was that the wifi was not working during all the staying and, despite Claudia made gentle efforts to make it worth, I could not use it.
Overall, I recommend this location.
