Me and my parents stayed at Roberta's place for 2 nights during our vacation in Rome. I did not meet Roberta in person but our communication were great! She was really responsive to my questions. Michaela waited for us in the apartment and explained everything. She doesn't speak English but everything is understandable.
Walking around is convenient. There's a nearby supermarket in less than 10 minutes by walking. Though I did not use Metro but the apartment was accessible from Metro (Manzoni station in less than 5 minutes walking distance). The apartment itself was clean, cozy & comfortable. Elevator was really helpful. I personally LOVE the interior design! Facilities were great & complete, particularly the kitchen & bathroom. There were foods provided, such as milk, biscuits, rice, tea, coffee that we can consume. Roberta also put a list of important contacts such as taxi. Our concern was just that the bathroom door somehow could not be closed. And the heater was apparently not warm enough since Rome was raining the other day and my parents were not used to cold weather, which is happening in most of Europe these particular days.
All in all, I had a great stay in Roberta's place and would recommend everyone to stay at her place and feel the Roman holiday experience.
