Alessandro's place is a perfect place to stay in Rome !
The neighborghood is great (a lot of good restaurants, cafés, vintage stores) and quiet (I've never sleep so well since a long time:).
It's in the center of Rome and you can do all touristics things on foot (Colosseo, Villa Borghese, Chirchs, Ghetto, etc).
When we arrived, Alessandro gave us a very good map with all the streets - the Lonely planet card was not so exact. He told us all we need to know about Rome.
The appartment is absolutely perfect for a two, there is wifi, towells, hair dryer and soap !
Just in front of Alessandro's building, there is a coffee shop with delicious capuccino and food :)
It was very easy to let keys when we left, and the subway is next to the appartment, and only one station to Termini which is perfect when you go to the airport !
I recommand this place more than once and we'll come back !
Thanks Alessandro :)
