I had a great stay at this hotel up until the end. I checked out early in the am on Nov 7 to catch a flight around 6 am. Once I got the Oakland airport (15 min away) I realized I left my blanket in my room. I immediately called the front desk explaining the situation no later than 30 minutes after checkout. The front desk rep, Alex, said he sent two housekeeping folks to check the room and they couldn't find it. I KNEW I left the blanket there, so I asked them to check again. Still nothing. I decided to call again later in the afternoon. I gave a very detailed description of the blanket. It was a yellow and black handmade blanket with a portrait of Frida Kahlo. They checked again and said there was nothing there. At this point, I'm sure the blanket may have been stolen, so I asked the housekeeping manager, John, to launch an investigation with the loss prevention team. I kid you not, 30 seconds later, John miraculously finds the blanket. He says that I gave him the wrong room #. 1) I had the correct room # because I still had my key card slip with me. 2) How many yellow and black Frida Kahlo blankets are lounging around at the Oakland Marriott City Center? This staff is completely dishonest and unprofessional.
