The room we stayed in looks exactly as the picture. Even though there were other guests in the house, we did not have issues using the bathroom or the kitchen.
We didn't have the chance to meet Marì in person because we were out of all, but the check in was very easy and she was in constant communication to make sure we had everything we needed.
Marì's house is very well connected as several bus routes take you to different tourist attractions and back to the house.
