The apartment was really nice and cozy, exactly what you see in the pictures, with a great view of the city and with modern appliances. TK was very nice, we arrived at the same time and he helped us with our bags up. It was all very clean and tidy. As he well mentioned here, the apartment is on the 5th floor and it's a long way up if you have heavy bags.
It is really near the central station, a 10 minute walk.
The district is near Grunelocka, but it is not really a place where you see many Norwegians, but mostly people from the Far East, so if you want to feel a bit of this culture it is also good, since they have all their typical things there, from restaurants to stores.
He lended us two bike cards, but we ended up not using them, since it rained on the first day and we didn't have time in the following day
We had a great time!
