The apartment is in a great location, with great bars and restaurants within 5 minutes walk...you must eat at Da me, wonderful trattoria around the corner.
Even with the buzz of the local bars etc, the apartment is totally silent, you can't hear a thing even when you're out on the small balcony!
The heart of the old city is about 10 minutes on foot.
In short a really lovely place for a couple to explore the city.
Were I pressed for a downside, the nearest public parking is about 10 minutes walk away and costs €15 per day
