Exactly the apartment we wanted for our family vacation with three kids. Some nice surprises such as a selection of DVDs for lazy days - especially the Narnia movie partially shot in the same valley! Customer service by the owner was excellent, there's a nice restaurant just around the corner and a selection of restaurants, several stores and activities in Bovec just a couple of kilometers away.
And the whole valley with Soca river was stunningly beautiful! We'd recommend for anyone looking for an active vacation - biking, rafting, paddling, trekking, etc.
If you arrive late (after dark) from Ljubljana airport, consider taking the slightly longer route and arriving to Bovec via Italy. The shortest way over the mountain road is amazing in daylight but with all the tight turns it's slower, at least in the dark.
One note: The stairs leading to second floor/bedrooms are very steep - if you have toddlers you'll have to keep an eye on them!
