My husband and I stayed at Susanne's place for a somewhat unorthodox reason: we're considering a move to Stockholm and wanted to spend a week in a house in a residential area to get a feel for what "real life" might be like, away from the tourist spots. It was perfect for our purposes; the house is in a true family neighborhood, on a quiet street with little traffic, across from a school (so the most noise you hear are kids yelling and laughing when they come outside to play during recess). We cooked most of our own meals, and because this is Susanne's own home rather than your typical vacation rental unit, the kitchen was well-equipped with everything we possibly needed. (My husband was especially impressed by her nice Japanese kitchen knives.)
Overall, I think it makes the most sense to stay in Susanne's place if you're a family of at least 3-4 and you need more space than you can get in a hotel in the city. If you're coming to Stockholm for touristic purposes, just be aware that you've got a bit of a commute ahead of you; it's a 5-minute walk to the bus, a ~10-minute ride to the train station or metro, and then another ~15 minutes or so by train or metro, so if you can time it right, you can be downtown in half an hour. Uber service is available, although it's not particularly cheap; we took an Uber from Central Station to Susanne's home when we arrived because we'd just spent all day on the train and we were too tired to try to figure out public transportation, and it cost around $50 (USD). One nice thing is that there is a direct commuter train (Pendeltåg line 40) to Arlanda Airport from the nearest train station, Älvsjö, so that's the cheapest/most convenient way to get to/from the airport.
Susanne met us on arrival and gave us lots of helpful tips and recommendations for the area. One thing I didn't realize until she mentioned it is that the 2x Michelin Star restaurant Aloë is actually located within walking distance. (We didn't end up eating there because I think it costs something like $300-500 USD per person.) Being a residential neighborhood, there aren't a ton of restaurants nearby; most are in the Älvsjö city center, about 15-20 minutes on foot. We did order delivery a couple of times when we got sick of cooking; UberEATS had a decent selection, and I'm guessing there's probably a local Swedish service that has even more choices.
Final tip: if you come in winter, make sure you bring shoes with good treads. There was sleet/ice a few nights while we were there in late November, and not everyone in the neighborhood seemed to be equally good about putting salt on their sidewalks, so the streets got a little slippery. Just be careful! And bring good shoes.
