We enjoyed parts of our time at the Kontakt, but will not return. The spa and saunas are the pride of the hotel, and rightfully so: interesting, healthful, invigorating.
Disappointments: Many, and more than the good points. The food (breakfast and dinner) was decent, but only on the level of a good cafeteria...all food was prepared in bulk and in large quantities, so nothing was truly delicious or special. The rooms were uncomfortable, with a bed that squeaked very loudly...two beds were pushed together as a "European queen bed." Bathrobes were provided in the rooms for use at the spa and pool, but they were never changed. When ours became wet...they remained wet for days. There were no shower curtains, (eastern!) European-style.
The spa facilities...gorgeous! However...all instructions are in Slovak only (no English, German, French, etc. anywhere), the spa staff mostly do not speak any other languages...and the many posted instructions everywhere (in Slovak) are IMPORTANT. No footwear/slippers allowed! No swim clothes allowed (nude/towels only)! Towels and lockers and keys provided only if you ask for them (using sign language), etc. For us (adult and child), this led to much confusion and embarrassment. When my child (respectfully and quietly) entered the sauna or jacuzzi in a bathing suit, he was rudely approached by the spa attendant and literally yelled at. This embarrassed him, and he left the spa red-faced, unwilling to go back in again. So unfortunate!
