Casalaviulia was just perfect. i cant think of any other word to describe it. Although we didn't meet with Federico, there was his Mother in law to show us the apartment and she was very cute and helpfull. Apartment is cosy and comfortable for two. Location couldn't be better. everything is in walking distance . litterally everything . Federico also was very helpfull when we need it and contact was very easy.
I would recommend this place to everybody and when we come back to Rome we definitely will stay here.
