Having recently returned from a week staying at this hotel, I would definitely recommend it, and Senigallia to others.  The hotel was conveniently situated 5 minutes from the sea and 5 minutes from the old town.  The staff were friendly, the breakfast was good, unfortunately the bed was rock solid and not to our liking, the roof top swimming pool was a real novelty.  The room was especially well cleaned too, with Sky, a Safe and a Mini Bar, we felt it had everything we needed.  Sengallia itself is a lively town, with few British visitors, providing a real taste of Italy, with many lively coffee shops and restaurants to visit.  The architecture is interesting and the International Bread Festival in the castle grounds (Pane Nostrum) was a real bonus, bringing even more life to the town.  Definitely try the Gelato, and take a trip to the sandy beach for a swim, paddle, or scavenge with the locals for washed up shell fish! Overall, a good stay, definitely recommended.
