This modern apartment has everything you are looking for. The tourist attractions "bryggen", "fløyen" and "Nygårdsparken", and the Bergen Light Rail(tram), the trainstation, and the busstation are all within walking distance.
The apartment was very nice and in a good location. You can easily reach the center by foot in 15-20 minutes and there is a supermarket (opened until 11 pm almost every day) very near the apartment. The kitchen was well equipped. We didn't meet Erlend, but he gave us all information we needed promptly. We spent a nice stay in Erlend's apartment.
We greatly enjoyed our stay. The apartment was very clean, comfortable, endless hot water, fast wifi, and (for those traveling with children) had a Pokestop reachable from apartment. Erlend was always available by text. There is a good grocery store (KIWI) 2 minutes away and the apartment is about a 10 minute walk to train station and heart of historic center. My only regret is that we did not stay longer.
