When I arrived, checked in w/ no issues. Settled belongings & laid down. After 20 min room door swings open & loudly hits the engaged door stop then closes. Startled by noise & what happened, looked thru peep hole, see nothing. Re-engage door stop, pondered what just happened. 2 min pass & exact same thing happens however I hear whomever messing w/ card reader. Door stop engages! I get up 2 check, no one there yet the door is cracked open. I again shut it & look through the peep hole; nothing. Call front desk to ask if room is double booked & described both situations. Front desk said they would look into issue and call me back. I hang up & 3rd attempt is made to open the door, & door stop is ebgaged. Finally see lady w/uniform, (no hotel name or her name) asking a ? in spanish. I speak spanish & this was incoherent as to what was being asked. She kept pointing towards the restroom. I removed the latch hoping to get a better explanation as to why (housekeeping, if it was her position) did not knock on any of 3 attempts to enter the room. She looked in bathroom turned around and left down hallway. Stayed in room a couple of hours for frnt desk to call back. Nothing. Went to front desk& told manager about issue. Was offered a discount for the inconvenience & was told notes would be added. When I checked out discounts were not given and i had to rehash entire situation. Lady at check out was less than apologetic and acted like i was inconveniencing her.
