It's been fantastic to stay at this flat: very comfortable, cosy and with the "real" Norwegian spirit :-) Birger and Sonja really make an effort to make you feel at home. For travelers, it is a lovely experience to live in such a cute, ordinary street alongside locals. The apartment is also well-located, about a 5 minute walk from the seaside and 10-15 min walk to Brygge and downtown Bergen.
Everything in the flat is in great condition, there are a bunch of tools in the kitchen, an excellent fridge, great and comfortable bed and shower :-) The hosts are also very accomodating in terms of arrival time, check-out/return of the keys. (Also, 2 keys for 2 people were a real commodity!)
Overall, we can only thank the hosts and warmly recommend this lovely place to everyone! Especially if you want to visit Bergen among local people, be by yourself but also be close to everything that's going on.
