We have just returned from a beautiful weekend at the Sporthotel Achental. From the outside the hotel looks somewhat dated...but only at very fist sight! Once you're inside the hotel turns out to be a perfectly well-kept and charming place. Our room was very spacious, clean and convenient (we had room 334). A bit disappointing was the view from our window/balcony towards the hotel's second large building...instead of the beautiful landscape which sorrounds the hotel. But this wasn't a problem.
The first evening we ate dinner at the hotel and opted for the buffett at € 22 p.p. which was delicious. You can also choose for starters only / soup only etc. since there is plenty of everything and for us it turned out to be a bit too much. The best is the hotel's wellness facilities: beautiful sauna, nice pool, and an above-average fitness area. We loved it!!!
A minor problem as other reviewers mentioned are the flies - probably you have to live with them since the area of Achental is agricultural and there are huge cow paddocks sorrounding the hotel everywhere.
Overall it was a great experience: clean, professional staff, good breakfast and extraordinary wellness facilities - everything you can expect from a 4-star property in the countryside.
