Highly recommended (except if you have difficulties with 3-4 floors of stairs). If you can overcome those steps, you will be welcomed as a family member, get plenty of suggestions on what to do (and how) and an amazing breakfast.
The apartment I stayed was huge for one person, with airco and beautiful views of the streets. The view from the terrace is also amazing.
If even back in Salerno, I will surely stay here again!
