Two knocks: 1) After house keeping on one occasion the cleaning staffs left behind a dirty towel of their own on the back/shoulder rest of the room’s sofa bed/couch; just a minor issue. 2) Now this is a serious issue, albeit not entirely the hotel’s fault. Long story short, the floor in which we stayed at was filled with cigarette smoke even though the hotel is supposedly a smoke free environment. The smell was weak initially, but later became unbearable. At 11:30pm or so when we communicated the issue with the front desk, the hotel staffs said it was too late too handle the issue and that they’ll remind the guests on our floor to not smoke. Given the time, I didn’t request for a room change or anything at the time but did so early the next morning, which I was then told to wait until between 12pm-1pm. I’m assuming the wait was because there were no rooms of the same room type available at that time but one is opening up but only after the guest(s) checks out and house keeping takes place. Were there any rooms but of different room type available at that time? I don’t know. The aforementioned was my assumption, but what really happened should’ve been communicated to me (barring language problems then it’s entirely understandable but the staffs seem to be fluent enough in english). At 12:40pm or so I got a call saying that my new room was ready. The inconvenience was I had start my day late. Looking back, the staff should’ve reminded guests at check in about not smoking.
