We needed a place to stay for a couple of weeks in the Šumadija area in order to visit family members without imposing on them. This fitted the bill for us perfectly, though without relatives to visit I suggest that a few days or a long weekend is about long enough.
The hotel is situated on a hillside with pleasant views of Šumadija, and lots of lovely fresh air. It is in close proximity to Orašac (of historical interest as the site of the First Serbian Uprising), Arandjelovac (which has a good Aquapark), Topola (where is it worth visiting Oplenac), and a little further to Mladenovac. However, if you don't have access to a car this is a very isolated spot.
The staff at the hotel are extremely welcoming, and really do try their best to please and make you feel comfortable. The service was generally very good and the reception staff were particularly helpful (to name an individual as being really first class - Ana). The restaurant is rustic with delicious traditional food, though choice became rather limited as we stayed two weeks. However, the selection is perfectly sufficient for a shorter break of a few days. In terms of room cleanliness I would say it was probably one of the best places I have stayed, with beautifully clean sheets changed every other day.
There is not much to do other than sunbathe and swim, so bring a book or other entertainment. Note that there are only Serbian language channels on the TV, but the rooms do have DVD players, so if you like films and don't speak Serbian, bring your own entertainment. There is also free Wi-Fi, which was very useful. During the week the pool was very pleasant as it was quiet, but at the weekend it was very busy (we stayed at the height of the season).
The name is something of a misnomer. The word "wellness" (which is a very poor use of English in any case) indicates that this is some sort of health spa. It is not. It is a hotel with an outside swimming pool. But now that you know that you will not be deceived!
I have no hesitation at all in recommending this hotel for a short break or a "get away from it all" retreat. You will need a car and a few good books. Value for money is excellent and we left having had a very relaxing holiday.
