Alessandra and Gennaro are nicest persons, we spent a week there and totally enjoyed our stay! I cannot recommend them more =) and I hope we'll come again.
Trastevere is a comfortable area both to explore Rome and places out of Rome, there is Trastevere railroad station 5 min walk from the apartment, and tram stop nearby. Also you can walk to the very downtown, Trastevere Street is shady and comfortable to walk even in hot summer. There are few very good restaurants within 10 min walk from the apartment.
Room and bathroom are lovely - clean, newly refurbished and have all necessary equipment, including air conditioning.
Dog is very quite and friendly. I miss her! ))
