Since these are quite a lot of allegations and emotions, and being our policy not to be polemic with our guests we will not bring this any further even if felt insulted! It will be your review against the review of all other our guests.
While being surprised that such issues are brought up after you left and during the nearly 6 days with us (not charged for 6 hours earlier check-in, instead to keep you waiting) you did not manage to share your concerns, it leaves us in condition of utter dismay how such a high hygienic standard person will leave the place in such condition!!! The verbal remark from the housekeeping lady had obviously been simply an uncontrolled reaction triggered from what she saw.
For sure we thank you for sharing your point of view and will update the place description that guest may find it noisy during top season at open windows.
Regret if your business trip was spoiled and wishing you better luck next time.
