Stayed at the 5th floor. Spacious room with multiple amenities (hair dryer, cosmetics, coffee maker and kettle, great selection of coffees and teas) and most importantly a balcony with gorgeous view! The hotel is located approximately 10 mins walk away from Krupówki and bus/train station, on a quiet side street.
Breakfast is served from 7:30 am which might be too late for those leaving for a hike, but the hotel has an option to order an earlier to-go breakfast. Good selection of fruit/warm breakfast options, a small corner with local products. Options served can get a bit monotonous after a while.
Spa zone (saunas, hot tub, swimming pool) satisfactory, but can get crowded easily. Great saunas zone with a cold water tub in the middle. Prepare for kids splashing water in your face in the "main" pool despite kids pool being available right next to it. I'd recommend going early in the morning or right before closing to unwind after a long day.
In general, several things could be improved - for example the pillows (too small and very soft), water temperature at the spa... for a 5* hotel, I'd expect the spa zone to include water for guests.
