Even though we've never seen the main host Grzegorz, we lived together with friendly and hospitable family. :)
Our room was clean and tidy, had towels and space in the fridge. Location is quite good - next to the bus stop and max 10 minutes to metro. The bathroom was shared but it didn't make any difficulties. The neighborhood also wasn't bad, we were very happy about big store next to the house.
To sum up, we recommend this place for those who don't want big luxury and are looking for calm, clean, not expensive place to stay. In the end, it was even sad to leave this place :(
