The facility was fairly clean, and the staff polite. But the check-in process was overly cumbersome and intrusive in terms of a paper form they wanted filled out, requesting all sorts of irrelevant information.
Also, the rooms are small, and the bathrooms downright tiny! We're talking cramped to being little more than airplane lavatories!
The main advantage of this hotel is proximity to the Helsinki airport, with shuttle service - though that is not 24hours, either. If you need to stay near the airport, this hotel might do, but not for more than 1 night! There are other options that might be somewhat more expensive, but are clearly better values. The airport Hilton is one.
