“It was our first journey in a Scandinavian company” isn’t wrong, but, it is more usual to use/say “to a country” when referring to a journey to a place.

We arrived toin Bergen late at night, checked into the apartment and went to sleep.

## 2nd day ¶

Bergen was the first city which we discovered.

Discovered implies you did not know about Bergen’s existence and came across it only at that moment. As you were already there and you had plans it may be better to say you “explored Bergan”.

It is a really beautiful city with toy multicoloured houses.

To go everywhere with an umbrella is not convenient, but a. A good raincoat is a perfect idea.

You can choose to visit sights suitable for you.

We were walking onin the historical part of the city for several hours.

Walking “on” means physically on top of something
Walking “in” is around a city/town/place/building

PartThe area with old wooden multicoloured houses seemed more attractive forto me.

Also: The area with old wooden multicoloured houses was the most attractive to me

We wentlooked around, this area, including inside the houses, and imagined how the city had been many years ago.

Went around is not incorrect, but look around sounds better.

HereListed below are several sights belonging to an old part of Bergen.

The Fishmarket in Bergen ¶
¶
Bergen's famous  Fish Market suggesterves/sells the freshest fish and seafood.

I am not sure what you are trying to say here?

Perhaps “Bergen’s famous fish market serves the freshest fish and seafood”?

Perhaps “sells the freshest….”?

It is one of Norway's most visited outdoors markets, which is good. It was suitable for us to get dinner.

Again, unsure what you are trying to say. I have worded to what I think you are saying based on context.

We had a tasty dinner in Fishme restaurant which is located in the market with nice view onver to/over looking Bergen’s multicoloured Bergen’s houses.

It is not a cheap place, but we had are on holiday and wanted to enjoy our meal in a beautiful place.

VilVite - Bergen Science Center ¶
We visited VilVite due to hugeeavy rain and had around 2 hours there.

Also: We were there around two hours.

There areis a lot ofor children to do, but it is interesting for adults also.

“There are a lot of children” means many children.

I took from this context you meant there was a lot to interest children as well as adults.

It works untill late evening, and we visited it last.

“Till” is the item the checkouts in the shops.
“ ‘til” is a colloquial usage of “until”
You will hear “ ‘til” in spoken English, however, it is not correct to use “ ‘til” in written English unless in a quotation of something someone has said.

If the weather is good, you can buy an one-way ticket and walk down through nice places.

Missing article “the”
Incorrect article “an”. Usage of “an” in front of a vowel is normally correct, however, not with “one”.
