For my 15 year old daughter and me it has been the perfect match: exciting citytrip mixed with great rest and relaxation time due to the very nice and spacious appartement and garden, all situated in a quiet and charming neighbourhood with extraordinary culinary temptations (we enjoyed a lot Gori Gelati and the Piadineria). For this I gladly accept rides in crowded buses in which you get in real touch with locals :) (well, coming from Berlin we're also used to this kind of transportation.) The buses come frequiently and go directly to all the hot spots in the center and then there is still the metro nearby ...
