Fitness 24 Seven, Plus

It’s far from ideal to have a gym split up on two floors — and the floors aren’t even that sizable — but the machines are modern (although the selection is limited) and the dressing rooms and showers are tidy. There’s also rooms for classes.
Fitness 24 Seven can maintain low member fees partly because they don’t utilize a lot of staff — so if you are a non-​member who wants to just drop in, you have a limited set of hours during the day to do so (when the reception desk is actually manned.)
One-​time admission is 90 SEK, while a month’s full membership is only 199 SEK — so you know they want you to sign up for a full membership (if you visit the gym more than twice a month, you’ll save money as a member).
Becoming a member takes a few business days, but once you have it you have free access ²⁴⁄₇ to ALL of their gym facilities, plus classes (boxercise, body pump, etc.) are included in the membership! It’s an all-​you-​can-​eat buffet of fitness!
The bad is that when a weight lock goes missing, it’s gonna take weeks for them to produce a new one — and without staff present, many members don’t bother to respect the equipment or people around them.
