I had a wonderful trip to Stockholm. Julia and her mom were so kind and lovely so it kind of felt like staying at home. The description to the appartment was perfect so I had no problem finding it. You reach the appartment in about 10 minutes so it's very near from the center and very convenient to stay there.
I really can reccomend to stay with Julia and her mom. It was the first time I used Airbnb so I was pretty nervous but they were such great hosts so it was a wonderful experience.
