We stayed in Luxury Domus in august 2014. The sun in Rome was very hot and the air conditioning in this appartment was great. The appartment is clean and nice. Not too big, nor too small, for our family of four (two kids). It basically has everything you need! The nights are quiet, no street sounds, so we slept very well.
Nearby are a good supermarket, a great Italian gelateria (ice-cream), some nice restaurants. And important: the appartment is very nearby the metro station (Manzoni), which enabled us to travel all through Rome easily.
Both Roberto and Luigi are very nice quys. Helpful and friendly! Very good place to stay in Rome! Recommended!
