Great location (centre of town, close to boat/ bus/ restaurants) and ambience.
Warm welcome and thorough explanations and tips, after which you are mainly on your own, so great for independent travelers.
Well-stocked fridge 24 hr a day, and free vouchers for a daily coffee & croissant at a nearby cafe. Famous pizzeria (Calvino) just around the corner.
Rooms are cozy and spacious, with clean bathroom en-suite and balconies overlooking the port. The 2 flights of steep stairs might be a minus for less mobile travelers or those with a lot of luggage.
