Just checked into a condo for the next 5 nights. It was very clean upon arrival but there are no housekeeping services. If you want new towels/linnens you must exchange them at the office etc. I am wondering why there is an envelope for gratuity for cleaning in our bedroom. Aren't the rooms supposed to be clean upon arrival? Nobody is doing any services for us on a daily basis for the next week. Am i naive? I don't feel a tip is necessary. Thoughts?
