I had a great time at Ewelina's apartment. It is a big, bright, and clean apartment. And the apartment is located in a convenient place. I just walked to KTH on foot and it only took me 15 min. If you plan to go to Arlanda Airport early in the morning, I will definitely recommend this apartment to you, because you can take train 40 directly.
Ewelina keeps the apartment clean and tidy, with a big kitchen and bathroom. By the way, the cute putty is there!
