There was absolutely nothing we didnt like.
Siderohori, where Iaspis guesthouse is located is a beautiful small village higher in a hill over Kastoria lake. Iaspis guesthouse itself is in a traditional style old house which has been fully renovated but keeping all the charm of the traditionalist style. Breakfast was lovely: eggs, butter, jam... all locally made. The owner is very friendly and helpful, we felt welcomed & comfortable. Our quadraple room was a separate unit on 2 split levels, with a fireplace & fully equiped kitchen area + small veranda/balcony on the front. The room was so unique and comfortable. Our son (12 years) was enjoying the stay too: the house, the room, the area.. The view over the whole Kastoria region and the lake is lovely and no other accomodation downtown in the town can replace it. We drove to the town every day, the drive is only about 10 minutes, we didnt mind it at all, on the contrary: having both town experience during the day and Iaspis for the morning & night it only enriched our overall experience on this trip. We warmly recommend it!
