We (my brother and I) stayed at Mai-Britt's for 3 nights.
The room was exactly as described and has it looks in the pictures.
It's a large attic, spacious, and well-lite. Comfortable beds, and very clean. Though bringing the luggage up there was a bit challenging, it's not a big deal.
There's a cattle to boil water and have your morning coffee/tea at the room.
Quick and comfortable access to the bathroom and shower (1 floor below).
Though we shared the house with other tenants, we hardly saw them and felt like we had the place to ourselves.

Mai-Britt is very nice and made us feel very comfortable around the house (going out to the terrace, using the kitchen).
The house is close to the beach, the Metro and several city buses.
You can even walk downtown- though it's a bit of a walk.. But if the weather is nice- it's doable.
