The booking process was smooth and Beata was very responsive and helpful. We had no problems.
The apartment is big allowing for privacy. The apartment is not luxurious but things worked, beds were comfortable so we were happy. It is also relatively close to the square (~15 min walk). The street was quiet and felt safe.
A few things that would make it a little better is to have some shampoo in bathrooms (any kind is better than none), also we got only one bath towel per person and one wash cloth for the entire stay. It would be nice to have a few extra clean towels.
