From the outside you could be forgiven for missing the building but once inside it is clean and tidy. The folks behind the desk were always polite and acknowledged us when we were leaving/entering. The room was a reasonable size with large windows, Aircon and a presentable bathroom. The breakfast was enjoyable, there was cereals, cold and warm meats, eggs, breads and spreads and various juices. A coffee machine, also. Some might consider it slightly basic but it suited our needs.
The location is the real winner. 5-10 minutes from the relaxed and fun Jewish quarter, 10 minutes from At Mary's church. We never needed a taxi and always walked. Our room was situated at the front facing the main road so there was some tram noise late at night but this didn't bother us at all.
All in all, we had a fantastic visit in Krakow with wonderfully priced digs. Recommend.
