Hello again, I’ve been talking with my colleagues, and apparently they have been doing some reforms in the building lately, so probably that is the reason of the smell, as we have got complaints from other apartments in the building today swell. They are working to solve the problem as soon as possible. In the meantime, I will bring you an air freshener today about 5:00pm, I hope it helps. My sincere apologies. この表現は自然ですか？
