Stayed 4 nights. Reception was extremely helpful. Especially as I arrived well before checkin time but fortunately were able to accommodate me. My room was spacious with both a safe and a mini fridge as well as a kettle. I would say if you're a tall individual the bed might be a little tight. I'm a light sleeper but generally hard very little disturbance. Garbage collection one early morning was a bit loud (outside hotel).
Breakfast was lovely with a little variety added to the hot breakfast daily. Certainly worth having. Go a little earlier as some things eventually run out with a later sitting.
The only reason I don't rate it 5/5 is there were some works on the 2nd floor on one morning after 10 am. Loud enough for me to want to leave. I had left earlier previous mornings so hadn't known this to be an issue. WiFi is good on the phone, laptop struggled. They also give a guest card that gives you discounts on many attractions, excursions and events including the thermal baths so take your swimming gear. Regrettably I didn't because I didn't know until after arrival.
