We were two colleagues staying in the Linnea room. The room was just as you would expect from the photos, with heating (we stayed in late March and it was freezing outside). Anne was a welcoming host who helped us get comfortable but did not overly bother us during the stay (and we mean this in a good way). The breakfast had a good variety and was delicious.
Location/accessibility-wise, Anne's Hus is conveniently located, 15-min walking distance from the airport shuttle stop / major bus stop Korsvägen-- ie. quiet neighborhood for sleeping but still close enough for city center commute every day. Although if you're moving in with big luggage, you might want to take the bus from Korsvägen instead of walk because Anne's Hus is up a small hill. One more thing to note, all the rooms are on the second floor through a narrow-ish spiral staircase, so it may not be accessible for everyone, and if you're carrying a 23kg suitcase up like I was... good luck (still doable; I managed somehow).
Bottom line: great host, convenient place at a reasonable price, but more suited for people traveling with light luggage / ok with climbing stairs.
