The fact that we had to leave :-)
Everything! The best traditional Italian breakfast I have had in Italy so far (wide choice of different home made cakes and croissants, fruit, yoghurts, fresh juice, ham etc.), free private parking provided, nice and warm staff/owners, unique design of the room as well as the house. Large garden and terrace where you can enjoy your breakfast with an excellent view. Longiano is a very pretty Italian town in the middle of wineyards worth visiting. We spent one night at Casa Dei Grilli heading further south and were so amazed that we booked another night for our way home in two weeks time. Guests have a 10% discount at a local restaurant (Osteria la Capannina) - great food, service and amazing views of wineyards. We will definitely come back to spend more time and stay at Casa dei Grilli. Perfect for biking.
