Upon arrival Antonia and I discussed the issue of sewer-ish smell coming only from the master bathroom shower and kitchen sink. She informed me that the smell comes and goes but is on going. While Antonia showed me around the areas affected, I was unable to recreate the conditions that caused the smell to come into the said areas. She stated she also was unable to smell it at this time. She inquired and signed up for the service membership. After running water (stated to exasperate/cause the issue) was not able to recreate the conditions at all. Stated she will reach out immediately if the issue arises again.
