Here in Stockholm hot desks are €450 and fixed desks are €550. Their hot desk proposition is pretty bad but for fixed desks they are pretty close to the market rate for central Stockholm if you want to rent 1-4 spaces, either in an own office or just desks. Their list prices for offices are a bit high but I know they can be negotiated.

Sure, you can rent for much less in the suburbs, but for companies who want an office which is central and easy to commute to the price is pretty close to market rate.
