Seeking a careful cleaning service for a thorough one‑time refresh (m/f/d)

I am planning a deep refresh before a busy period and would value professional support. I am looking for help with home cleaning in Köln. The cleaning is a one-time appointment on 15.03.2026. I expect about 4 hours of focused work. The area is 154 m² with 6 rooms, 3 bathrooms, and 2 kitchens. My budget is 14 € per hour. There are no animals. I appreciate care, efficiency, and a friendly approach. If this suits you, I would be glad to hear from you.
