Hotels in Sweden can be a very good deal if you book them during/for promotional periods or use points in some programs. And the hotels including a very decent breakfast and internet access is more or less a given with many hotels in the country.

Transport costs can also be very reasonable if you book in advance for rail trips, rely upon public transit means (sometimes with regional transport passes), and avoid using taxis.

Value for money when eating out is where having a small budget doesn't work all that great in Sweden.
