I stayed in this hotel for 2 nights and I am very happy to recommend it. We stayed in a room on the 1st floor (I believe No. 3) which was very spacious with even larger bathroom. The room consisted of a comfortable double bed and the sitting area with sofa, TV, fridge and writing desk. The room and the bathroom were spotlessly clean. We also had a balcony facing the little square in front of the hotel.
The hotel is located just at the start of the pedestrian zone of the town. It is some 10 minutes leisurely walk to the lake along the main street.
There is a restaurant in the hotel and the food is very good, I would definitely recommend to stay for dinner.
The owner/manager of the hotel was very helpful and booked some treatments for us in the Pax Hotel (I would recommend the Russian lady there for reflexology - what a treat!).
Overall, I give this hotel 5 stars. There are surely more luxurious establishments in Trencianske Teplice but this hotel is cozy, clean and very good value for money. I would definitely stay again.
