We had a very nice stay in Manuela's appartment.
The place itself was very nice, big enough for 3/4 persons. It is situated in a local area with a lot of shops, restaurants, food stores... It is also close to the train station that leads directly to Fiumicino airport. It's also close to the historic centre (20 minutes by tram or bus).
We were very well welcomed by Manuela who got everything ready for us when we arrived (keys, towels, important instructions, nice advices...).
If I had to come back in Roma (and I'll definitely come back), i would not hesitate to chose Manuela's place again !
