My parents and I stayed in this airbnb in the first week of August and it was perfect for us three for a city stay. The apartment is really close to the center, really well connected with metro and buses, on the top floor with a gorgeous view of Stockholm, just like the pictures. There is a supermarket and cafes and restaurants down the street and an amazing bakery "bullar and bröd". Checking in and out was super easy with a lockbox and Fredrik was pretty quick with replying.
Someone obviously lives in the apartment when it's not being rented out and there are a lot of clothes, personal possessions and kitchen equipment in various cupboards/fridge. These could be organized/tidied up a bit better/put into designated places so that others are free, or locked away so that its safer for the owner and you have less of a feeling that you're encroaching on someones house. The apartment is also a part of some kind of a student complex as far as I've gathered which also could've been mentioned - we were there in August so there was barely anyone but I don't know how noisy/busy it gets when school starts.
The tv is only in swedish and only has like five programs but there is a chromecast so you can cast your netflix/disney + etc. Theres also a lot of books and some games.
For someone who asks of their guests to strip the sheets, collect the towels and throw the trash out when they leave, they could clean the apartment a bit better as the microwave still had some food splatters in it, the window sills had some mug rings, bathroom cabinet had some hairs from shaving in the crevices, etc. It wasn't horrible and overall pretty clean but these small details make a big difference in the experience. There's also no water kettle so we had to warm up our water in the dirty microwave.
If these things are sorted its honestly an amazing place to stay for a good price, and the view really is the seller.
