You are already on the right track deducing that your price might be too low if everything books quickly. Pricing is complicated and depends on many things like holidays, events, and how many guests are looking for a given date.
I recommend you raise your rates closer to what’s comparable to others in your area, and see what happens. It might slow down bookings but often in a high demand area guests will snatch up the cheapest properties months in advance, leaving the higher-priced options to be booked later.
You might also consider varying your prices based on season. I would think in a place like Stockholm, summertime would be in higher demand than wintertime, and weekends would be in higher demand than weekdays. That’s just my guess. It’s a tightrope walk to set just the right prices.
In big cities with lots of demand and lots going on, a dynamic pricing product is helpful (like Wheelhouse, Beyond, or Pricelabs). This kind of product keeps track of holidays, festivals and events in your area, measures the flows, trends and volume of bookings as they happen, and dynamically proposes and/or manages the prices accordingly. They charge a small percentage of your revenue. I find it very helpful on one of my bigger city properties, where it would be difficult for me to keep track of festivals, business meetings, sporting events, etc.
To start, though, just start tweaking the prices, so that you can get a gut feel for the booking flow for your property under different circumstances.
