We stayed there for a weekend. Arrived midnight on Friday, check-in was smooth and we were helped with the luggage. It was extremely hot days (and nights) this July (about 35C during day), so keep in mind that there is no air-condition in the hotel! Lobby areas was over 30C. Hotel is refurbished, rooms are ok - standard size of Mercure.
It used to be hotel from Orbis brand. Usually staff in these hotels is quite "oldish" and thinking from 20 years ago, but I was nicely surprised that in Skalny staff was rather friendly and helpful. Big plus for the management.
Internet is complimentary and works fine. Free parking space is limited, secured costs 25 PLN/night.
Breakfast was regular, some food was not too tasty, but overall you can find something to eat for sure.
Hotel is less than 10 minutes walk to the main street. Even it was a weekend, still there were not so many tourists.
As I mentioned before - no aircon is huge minus for hot season.
Will come back, when visiting Karpacz again, especially with weekend rate of 240 PLN, it is not bad at all.
