Beatrice was an amazing host, she is a lovely person full of energy. Breakfast was great with great coffee, fruit, cheese, ham and homemade jam! Beatrice also gave us great advice about places to go.
The house is beautiful, the room as on the pictures. If you have a light sleep I'd recommend earplugs (like everywhere in Rome with a street-faced window ;) ).
The location is also great: Close to Termini (less than 5 minutes walk), but you do not have to walk in an empty/dodgy street/area from there to the house. We (2 girls) never felt unsafe even when we walked home during the night.
Would definitely stay there again!
