We stayed at the Bella Rome for 4 days&nights and it was great.
The house is in a great location; in a non touristic area and 2 min. walk away from the metro station. There is a super market next to the house and there are nice cafes, shops etc. in the neighbourhood.
Cristina and Raffaelle are great hosts; they met us at the metro station and guided us to the house. They prepared a basket of food for and they even thought about our breakfast :)
They explained us the metro&bus system, advised us restaurants (great ones we must say), and even send us an e-mail including the details of touristic sights and airport transformation details. They were kind, helpful and ready to communicate whenever we had a question or needed advise.
The house itself is in a very good condition, very comfortable and very clean. The kitchen has everything you may need, there are 2 large bedrooms and the bathroom is large&clean with a shower.
Overall, we would definetly recommend Bella Rome and we would stay there again if&when we go to Rome.
