We stayed in the Rzeszow apartment on the forth floor. One bedroom apartment and it was huge.
The main room (bigger than most hotel rooms ) had comfy sofa, dining table and 4 chairs, king/twin beds, couple of display units, desk and chair with a computer and large flat screen TV.
There was an ante room next door which had a large comfy chair, desk and chair and stairs leading up to 2nd bedroom.
The stairs up to the bedroom were very steep and oddly shaped but once I got the knack managed fine but they would be difficult in mobility problems. There were 2 smaller single beds here and a dresser. The beds and pillows very comfy.
Back downstairs there was a kitchenette with table and chairs, most things you would need to make breakfast and light meals. There was also a dishwasher and fridge. The built in wardrobes were next to this and there was a safe in the room.
The bathroom was roomy with a powerful shower and clean towels each day.
The reception staff always polite and friendly.
Excellent location. A few minutes to Galeria Krakowska (where there are supermarkets) and the train station and less than 10 minutes to Rynek Glowny. In fact everywhere was within walking distance.
My minor criticisms were the rooms could get very hot and if windows open noisy from the bus stop outside. With being in the roof space/ attic it tended to get a little dusty. A few scuff marks on the walls that need a paint touch up. The TV despite having satellite channels the only English speaking channel was BBC world news. I am waiting for a reply to my e-mail about this.
Finally if I come back to Krakow I would definitely stay here and would not hesitate to recommend it to future travellers.
