I recently spent 5 days at Klavze 28 and it is easily one of the best trips I've ever been on. The trip to the house was filled with spectacular views of the area and then you arrive to the house itself! It's gorgeous. The owners were so welcoming and they had truly thought of everything (as far as I could tell) when it came to the comforts of travel.
The food I had at the B&B was the best food I had during my stay in Slovenia. We were treated to local trout from the river running through the property to a love-filled mushroom risotto. The breakfasts each morning were made with fresh eggs from the property as well. Now that I'm home, I really miss having all of that great food waiting for me with no effort on my part!
We had a car on our trip so we were really able to explore the area. The owner of the B&B recommended a local outfitter for a canyoning trip nearby and set us off on the right path daily for the sites we were headed off to see. Those included: touring the nearby wine region, a trip north to Lake Bled and Bohinj, riding the car train back from the north, a trip to the coast to see the beautiful sunsets in Piran, touring the caves and castle in Postojna, and just the day to day places just next to the B&B including Most Na Soci and the local honey merchants. It was all so gorgeous and prestine.
I keep telling people they should hurry to Slovenia before everyone catches on! Definitely give Klavze 28 a try if you decide to take that advice. It was great. I'll post pics to show what my room looked like.
