Ooh, my first moxy stay, it's even noisier than at alofts in the lobby.
Bed is pretty small for 2 persons, couldn't sleep good, don't like the mattress.. room is basic but nice TV. As op said it's ok if u need sleep and nothing else. No restaurant on site. You could walk to element restaurant but can't recommend that either. They have one hot dish every day at the moxy. Staff could be a bit nicer, they kinda have this we Are so cool W hotels attitude.
Prices at the shoop are rather steep, 5 euro for a 0,2 l bottled juice is over the top for this brand I think.
Well, I stayed here for thr megabonus... Wouldn't stay here for any other reason as there are so many options around....
Hyatt place will open around the corner next to element, looks pretty finished from the outside.

My rate included breakfast for one person, I had a charge of 20 EUR on the bill for breakfast.. It is only 10 euro though... They couldn't fix the bill within 15 minutes so I have to follow up by email.

Another thing which isnt relevant maybe for the most here on ft.. but i expect to be able to communicate in German in a hotel in Germany... most staff were not able to do so
