The appartment consits of five rooms in total, of which most are rented out long term to exchange students. So, in case you plan a longer stay, it might be worth it contacting Tania directly.
Since most tenants live there long term, the appartment has a shared-flat vibe - so don't expect everything to be super tidy all the time (though I'd consider it reasonably clean during my stay) or super quite during the evenings and weekends. Before and after somebody moves in/out, a cleaning lady is tidying up the common areas and the respective room(s). During the stay (if long term) you have to clean it yourself - at least I did - it really is a shared flat, so to speak.
I brought my bike to Stockholm and can only recommend doing the same. By bike it takes around 15 minutes to get into the city centre and the house offers a bike room as well. To my workplace in Solna it took me around 30 minutes by bike - only half as long as it would have by public transport. So big recommendation!
Public transport is also very close, with two bus stations only around 5 minutes away, through which you have acess to Liljeholmen and Gullmarsplan.
Tania as a host is super nice and always happy to help, but does not live in the appartment herself - so don't expect her to be around. Especially when i arrived she was a big help with guiding me to the apartment.
The biggest downside for me was that the room does not have a table/desk. So if you want to work at home, the only option is the kitchen table, with the downside however, that people are entering all the time and disturbing you. This is also one of the reasons why I opted for another place for the rest of my stay in Stockholm. The other reason beeing the price - but it must be said that it is also quite hard to find cheaper places in Stockholm, even if you start searching early (I searched for almost half a year prior to my stay). Renting just isn't common in Stockholm/Sweden. So in case you can get a long-term agreement with Tania, like living together with other people and don't rely on a desk, I think that is a very suitable way to go.
