We're not difficult to please. All we ask for in a hotel is ac/heating that works, a bed that's reasonably comfortable and bug free, and working plumbing. The Residence Inn did not meet those expectations.
Toilet didn't flush at check-in. Didn't want to move to another room on another floor so I borrowed a plunger. After a few minutes of working it more or less lazily flushed; there were black metallic scratches in the bowl indicating that it had recently been snaked. Went to bed. Woke up the next morning: no flush, just a lot of swirling water. Went back downstairs, borrowed another plunger, worked on it again until it flushed. Then we checked out.
This room should have been blocked rather than renting it; I understood from (undisclosed staff members) that plumbing had been an issue for some time.
Desk staff was friendly, apologetic and accommodating throughout.
