You will not be disappointed if you rent the apartment, and the location is great. Pietro is an exceptional host, the place was spotless, and there were some thoughtful [unadvertised] additions; namely water, fruit juice, beer, coffee, pasta and pasta sauce, supplied upon arrival.
The sight of the Castle opposite the accomodation never failed to blow my mind every time I stepped onto the balcony.
The surrounding area itself has a slight bohemian feel to it, and is within close walking distance to shops, pubs/bars and restaurants. It's vibrant yet calm, the only thing you may be overwhelmed with is the wide choices of places to eat and drink.
