I did not stay with her. I stayed at Tourist Farm Kranjc, which is near Drežnica, which is above Kobarid. Vesna has just two rooms to rent; it's worth noting they share a bathroom, which may turn off some.
Hiking is high on my list of interests, so that was a major thrust of our time together. I also expressed an interest in beekeeping. My days with Vesna were as follows:
Day 1: I drove up from Piran and met her at her Homestay at 10 am. She gave me some herbal tea, and then we set out for the Brda region in her car. We visited a beekeeper (included a honey tasting -- who knew that was a thing?), climbed a tower with great views over the region, visited Šmartno (a small medieval walled town/village), had a great lunch in a 2-3 table restaurant with a lovely owner at the village (included drinking a glass of orange wine), walked through vineyards (eating grapes straight off the vine [it's legal, so she tells me] and other fruit along the way), went back to the Homestay, traded her car for my car, and drove to Tolmin Gorges for hiking. I dropped her off at a bus station at about 5:30 so she could catch a bus back to her village while I drove on to Koseč.
Day 2: This was mostly a hiking day that included a visit to the very cool Memorial Church of the Holy Spirit at Javorca (one of my requests). She met me at Kobarid at 8:45, and we finished around 5:30.
