I stayed in Marlena's apartment for a week. The apartment is located in residential building construction 22 minutes from downtown via train. Pleasant, warm, and cozy, and equipped with a comfortable bed, a desk, and a closet. You can use the kitchen freely and also have space in the refrigerator.
The neighborhood offers everything: shops, markets, pharmacies, grocery stores, supermarkets, etc. It was pretty helpful and economical to buy in these supermarkets since, in general, Stockholm is rather expensive.
Marlena is a super friendly and talkative host. I highlight that she is pretty unproblematic and straightforward. I felt at home in her apartment.
I strongly recommend staying in this apartment.
