We work very hard and always strive for 100% satisfaction. The guest’s wife/ partner checked in and was completely satisfied and happy. We really were puzzled by the last guest’s remarks and had no idea what he could possibly be referring to! Some people can have a fixation with the strangest, smallest, most minute detail, and you just can't please them! We have highly mineralized water that leaves a very slight, small amount of residue that some very fussy people may possibly MISINTERPRET to be a not properly cleaned faucet. This is not the case though.The residue just cannot be removed with bathroom cleaning solutions but still is completely clean. When you move your hand over the surface it is clear that everything is completely clean. The apartment was cleaned for 2 days by myself, my partner and her sister. It was completely clean from top to bottom! If you moved your hand over the floor, counter or any surface it was completely clean. We will search for something that removes this small residue without damaging the fixture. The guest seemed annoyed that he couldn’t reach us, however our contact email and phone were prominently posted on the fridge door, but the guest did not use this information for contact as indicated in the note. We received no call, text or email. We can always be reached by email.
