Other Hotel Programs - Allseasons Frankfurt?

Any impressions if this hotel is worth staying in? I have option to go for this or for IBIS Frankfurt Centrum for 10€ less.

Can't say I do, stayed at the Savigny Hotel Frankfurt City before when it was a Sofitel (not up to the Sofitel standards and since relegated to an Accor hotel without a chain strangely enough). Good enough though as 3/4* especially considering rooms go for € 60.
