I stayed in Kransjka Gora during the summer, and even though the area is best known for the winterseason, the summer is also a beautiful time to stay. We had beautiful walks, rented a bike and had a really relax time in the apartment.
The apartment has everything you need to really enjoy your vacation. It is modern, has loads of TV-channels, a balcony with a gorgeous view, a kitchen with all the equipment you need. Even though there's plenty of lovely restaurants, you can also choose to cook your own meal, since everything's right there.
The apartment is located in a really quiet area, which makes it the perfect place to relax after a long day of hiking.
Other than that, the apartment was well-cleaned and the bathroom looked really nice and clean (I usually look at the bathroom to see if a place to stay is any good).
The owner is really helpful as well, Helena knows everything about the region, and is always prepared to help you out when something's wrong.
Overall, I would definitely come back here, and also recommended the place to friends of mine.
