I was very positively surprised. Reviews were mixed. It was much cheaper than the other spa hotels, so I wasn't sure what to expect. Yes, it's a bit rundown, scrapes in walls, etc. But very clean and very comfortable. Receptionist was super friendly and helped me with anything I needed. The room was adequate, bed very comfortable, bathroom in good shape. My room - the cheapest available - had a terrace with gorgeous views.
Yes, there is sulfur smell throughout the hotel - it's a spa hotel with thermal bath, so it's obvious. That's why you stay at that hotel.
The thermal pool was awesome. Very relaxing and it really helped with my sore muscles.
Dinner and breakfast were nice, service very fast. Breakfast included, dinner is an ok price. They promote healthy food but also have various choices of breads and sweets for those who want.
It really feels like home, cozy and friendly.
You are right by the public bus stop and right by the castle and entrance to the old Town.
