I spent two nights at Bruna's place, it was great! Bruna is very kind person, even though she speaks a little English we could understand each other well. In any case you could also contact Valeria, who organizes your check in and even help with communication with Bruna.
You have an amazing room with private bathroom and terrace with a view to Vesuvio! The comfy bed, table, own fridge (!) and something for breakfast like cookies, tea and coffee.
The location is nice too, there are two metro station near by, Museo and Materdei.
I would recommend this place to my friends, and would glad to come back there again!
