Small update after 3 years, hotel lost same space on ground floor - no more night club with live music, no more old restaurant - they build new wall in corridor on old entrance from square 'Trzech Krzyzy'.
We came by our car to hotel and it was no space at front parking, I need park at front of main entrance, we have 5 pcs of baggage and nobody came and help us I must quick put all bags on sidewalk and look for free space to park on next streets. When I back my wife still with all bags wait on front of hotel, ok we bring all baggage to lobby area by themselves and I want ask FD if we can have upgrade to niece suite with view on square she told me that it is possible she will have free two suites later when guest will leave it /it was 2:30pm/, she told that she allocated this type of suite to me please came later and you will have it.
I want put our car in underground parking /at weekend parking is free of charge/ and I want leave our baggage in deposit till our check-in. Still no bellboys to move our bags and woman from FD take bags to deposit.

We go to old town and long walk back to hotel at 6:30pm at FD was new staff and he check us to standard room, when I see number of room I know that this is not this what I ask earlier and I loose 4h on waiting for this type of suite. FD staff answer that only one of suite will be available but still guest not checked out, second suite was sold, if you want it you must wait - we go to lounge for one hour, at 7:30pm again I go to FD and ask what is situation - answer was ok, guest leave it but we need clean it and you must wait but I can give you standard room for this time ... I think that he cheat me and want cancel our stay and move to Westin but it was prepay booking and we will lose our money or we will continue wait. We go to park Lazienkowski for next walk and back at 9pm to FD and this time our suite keys was ready.

Underground parking is free of charge for hotel guest on weekend /Sheraton and Westin, but at Moxy you need pay 45PLN per day and if you have at beggining cheaper rate after adding parking cost you will have this same cost as Sheraton or Westin at weekend days/
Club lounge is closed and all service of club lounge moved to restaurant where you have served breakfast.
Bellboys are fired from this hotel ??
You will have at checkin breakfast as Platinum benefit and points or local gift.
After closing night club is quiet evenings nothig to do as in Westin, really missing live music.
