Spent 5 days at Astera Hotel in January 2019, as an alternative to another hotel nearby, where we could not find available rooms in that period.
The good: SPA and indoor swimming pools, large room, fairly clean, close to the ski station (still, not easy to walk with the ski equipment on), but they run a shuttle bus for that
The bad: outdated rooms (need to be refurbished), restaurant ambience and food, cold food is regular (almost everything was served cold: breakfast eggs, dinner plates, etc.), poor quality breakfast (very cheap food), always leaving with a strong food smell impregnated in our clothes, overall feel of dirtiness (glasses, table cloths, etc.).
As a personal conclusion, the hotel has good potential due to its location and facilities (the SPA and room size), but it requires urgent refurbishment and improvement of management, especially for the restaurant.
