Have given Krystina 5* as it is a great apartment in a great location and Kyrstina/Olga were quick to answer queries, would recommend this place and go again. It is worth noting there was only one set of keys between 5 of us which made things difficult in the evenings when people have different plans and lights out times. (I am sure this can be rectified). There was also a large crack in one of the big windows probably 50 cm by 50 cm which we were not informed about beforehand which we only found on our last day doing a clean-up because it was behind one of the curtains, these things need to be communicated upfront.
