Upon arriving after 7pm, housekeeping arrived to clean up from a maintenance visit to repair a plumbing issue prior to KY arrival. Unfortunately, they didn't and I was woken by noisy pipes in the kitchen at 5am which lasted an hour plus. I complained to host front desk. Maintenance again visited to "fix" the problemand left a nasty, smelly sink behind. I again complained and while their cleaning staff alledged to have returned to clean up after maintenance the kitchen sink was disgusting covered in a black gunk. This continued throughout my stay. At no point, did the host even offer another unit or other accommodation. After not being able to resolve the issue, they stopped responding. I finally contacted a Manger atthe Signature who stepped in the night before my arrival. It improved the situation but I feel bad for the incoming guest
