We stayed 3 nights in Krystina's house, the place was very nice, big room with a balcony, she provides us coffee and we could use kitchen utensils and cook. The flat is not far from the city centre, 2 or 3 stops by metro or 30 minuts walking. Krystina was kind and helpfull, it was very easy to find the appartment with the directions she gave us. Overall a great experience.
