The location was perfect; 5-10 min. walk to the railway station and bus station, a big shopping center 5 min. A small supermarket across the street, very good. 10 min to the old town, 30 min to the Jewish part of the town.
A friendly guy fetched us from the railway station, while we could not find the place in the beginning (our fault).
Nice kitchen with necessary things for cooking and eating. Very comfortable mattresses but only one cover per twin bed (the covers were wide enough though). Nice bathroom with a bathtub.
Although the apartment seemed to be brand new, we were missing some basic stuff though, like hooks for towels in the bathroom, a clothesline for the laundry (the drying rack did not warm up), dish soap, salt and maybe a little more space.
The Jewish part of Krakow was WONDERFUL!
