Stayed in this appartment hotel for 3 nights with my wife and daughter in jan 2013. We took the room which could easily accomodate 2 adults and 2 kids. Payed for it around 550 euros ( including car park). The room was clean. Scandinavian quality. 4 stars. They did not clean it every day. That was minus. Convenient undeground parking. Breakfast was ok. Limited in assortment. It was my third hotel in sweden and finland. Sky hotel was in line with others. The good thing was that the hotel was located 4-5 minues away from 2 metro stations. 3-5 metro stops to the center. Free wifi.
On the negative, i would mention only that if someone cooks on the floor, one can smell the flavours. Remjnded me of a student hostel-).
Apart from that, i would reccomend the place for families with kids teavelling by car.More
