Definitly a place where I'd love to come back. I was there just for 2 days, but we spent more time at the house than walking in the city. Rome was very crowd and grab a bottle of wine and drink in the terrace while eating something at sunset made us fell in a movie. Better than coloseum, fontana di trevi or whatever.
It is a very very beautiful house, with a incredible design. Also, I love cooking and the kitchen is a real kitchen fully equiped to cook whatever you want.
Elena is a great host, she helped us with issues that she didn't need to and it was very important for us.
The house is less than 5 minutes walking from the train station that comes from the airport. It was great also.
Dont think twice if you are in Rome.
