Kinga's apartment is just perfect! It is lovely, it has everything you may need, it is comfortable (the air conditionner is a ++), spacious. We were 4 friends and we really liked our stay there. The city center is easily accessible by metro and the area is quiet.
The owners have been very nice and we have had an easy communication. We appreciated that they took time to explain us what we needed to know about the flat, instead of just leaving us with the keys.
We recommend! :)
