Valentina is really helpful and friendly. She responded my queries really fast and was always in contact to know if everything was ok in my staying.
The place is near the old city (15 minutes on foot) and super close to the train station.
Just be aware that the place is on the third floor and there is no elevator in the building. It wasn't a problem to me but it's always good to know it to avoid unfair compliments.
I totally recommend Valentina's place.
