The hotel was clean and somewhat spacious since I got the XL room. Reception staff was friendly. Unfortunately twice I was disturbed even when I had the DND hung outside room door. Once was just after 1pm (they knocked my door to see if I still needed housekeeping) - actually 2 staff of which one seemed like a supervisor. AGAIN next day, same notice hung out, but I got a phone call in room (just after 12pm) from HSKP manager mentioning that I have a DND hung outside, do I still need my room made (of which I said no thank you). I come from this line of work and know clearly you should not disturb the guest in any means other than a note thru the door. I thought this was standard SOP, maybe it's not in Frankfurt? Maybe I expected too much. Another technical frustration was the auto sink faucet. The sink was as shallow as a plate, the auto faucet would splash the water all over my clothes(and the whole sink area). Seriously annoying. Sometimes it kept splurting when no one was in the bathroom. U know that would spook anyone out right!. Otherwise, there is a nice shopping plaza beside the hotel. Short walks from U/Trains. The place was clean. Just honest feedback from my experience only.
