Frederico's place is very strategic. In between 2 metro stations, near a tram line and there are buses stopping in front of the street. Some of the attractions are within walking distance. Anywhere in Rome is within reach from here.
I shared the apartment with Frederico and another guest. There is a common bathroom and kitchen that is quite well equipped and stocked for cooking. The illy coffee machine was great for a wake up boost in the morning. Plus the washing machine was handy for a long stay.
Frederico is usually around so he can share with you some tips if you need them. Very friendly and helpful.
The room itself could be improved if it has curtains for privacy but you can change in the bathroom.
Trattoria Fusco just down the street is highly recommended. The spaghetti carbonara is superb.
Will gladly recommend and stay again.
