Great location (if you don't mind the train). Took about 30 minutes to get to the city center from the apartment which may be far for some people, but was fine for our stay. The unit is very spacious and open. Very clean with good natural light. The beds were comfortable, the back porch was pleasant if small. Few stairs to walk up (big plus after a long day walking inthe city).
Note, no microwave or oven, so if you want to cook the only option is stove top. The coffee maker is nespresso so it limits the type of coffee you can get. There is a grocery store nearby and a little cafe that is worth a stop in. Cool little parks and gardens in Bromma that are worth checking out.
The host was very responsive and helpful. If I go back to Stockholm I hope to stay here again.
