Good hotel, spacious room, well equipped, clean. On the main pedestrian street, though a bit of a hike from the port, some 20min walk.
Not sure about the 4 stars, but very solid 3 stars sure. Reception a bit chaotic, first they told me the room not available and I need to wait until afternoon, only to come in 5min to say that the room is available - I'd expect them to have a better grip.
Overall a good place to stay and based on my 1-night stay I wouldn't have a problem coming again.
