The apartment is great, with a personal touch and soul. We were lucky to meet Denyse in person, despite our flight was late and we arrived late at night, she greeted us hospitably with a lot of great recommendations.
The location of apartment is perfect, you can walk to another parts of Rome easily. It is lively at night, but nothing bothered our sleep. Trastevere neighborhood is beautiful, with old churches, cobbled streets, some good traditional restaurants, but you have to choose carefully to avoid tourist traps and enjoy roman cuisine.
The city is not overcrowded in December and we really enjoyed going off the beaten track, visiting Testaccio market, photo exhibitions in Museo di Roma, Centrale Montemartini and some new places with great food and wine.
