Wifi is not so reliable. If you bring un-updated Windows PC, you must be careful or put that trash in the grabage can - but the same time, the room doese’t have garbage can ( a small one is in the bathroom).
But anyway, people are friendly and a breakfast is just great. Hotel’s restaurant closes a bit early in night, but you have a small food store (that you can buy beer or more) very near the hotel.
Also a location is good, not so far from an old city center or Poznan congress center (if you come to this town for PGA), so that you can walk to go there.
Strongly recommended if only you have a decent portable Wifi, or you are not here for business. For uploading some nice photo on SNS or chatting with friends, Wifi here is strong enough.
