Olga's place is located just steps away from the leather market and 10-15 minutes away from the duomo and the train station!
Olga does not speak English very well so it was a bit difficult to communicate once we got there. However, speaking through text and the app was very easy with translation services.
The room is very private with a separate entrance. We only say Olga when we arrived and she left us to do our own thing which was great.
The only negative was the bathroom is extremely loud and there must be something wrong with the pipes because it makes crazy noises.
