Unfortunately I didn't meet Magdalena in person, but she was very good in communication by e-mail (fast and detail-oriented). I've got all necessary information about apartment and how to get there.
The studio itself is on the very beautiful street Polska crammed with magnificent Art nouveau style buildings. It's not far from the heart of the city and I was walking there without using public transportation (which is also available nearby).
Studio is quite big and pretty, clean and featuring all necessary for a pleasant stay. It's a little bit pity that the studio is on the half-underground level, but this fact is compensated by the beautiful outdoor patio on which you have an access.
