We, 2 adults and 2 kids (6 & 12), stayed for a night, on our way from Oslo to Gothenburg and Liseberg.
The room is rather small, with one comfortable bed for two adults, and a sofa bed for the kids. Nothing fancy, but all what we need for a quick night stop.
We did not test the dinner at the restaurant or burger joint, but had some snack at the convenience store,and we got what we expected.
Håby doesn't have much to offer, other than this, but me and the kids did have a walk around the area and into the woods,so it's possible to do a walk in the areas.
The breakfast is nothing fancy, but a small wariety of bread, Knekkebrød, vegetables, cheese, spreads, eggs, meatballs, sausages, eggs milk, juice, yoghurt, coffee and some pastries.
We payed aprox 900 SEK, for the room, breakfast and parking, which is nothing less than a bargin!
So if you just need a short night's stay, along the highway, and nothing fancy, this is a great place to stay.
The noise from the highway, might6be bothersome, we had one of the rooms closest to the highway, but it quieted down a bit in the evening, so I didn't bother.
