Black Diamond Mines Regional Preserve, California hotel rooms at the Marriott Hotels & Resorts

"Water coming from floor"

"Clean room"

"The property was beautiful and the rooms seem to have been upgraded. Pleasantly surprised that there was a microwave in addition to the minifridge. Ate at Pivot and the portions were large enough that we had leftovers for the next day. This is our new favorite property when we visit the Tri-Valley."

"Very strange check-in encounter. After confirming I booked/paid for a two bed room with a pool I was given the option to wait for my room or choose a room ready now but without the view. I told them I’d wait. An older Indian gentlemen’s came over and told me they don’t have anymore rooms with a pool view or rooms with 2 beds. Confused I told him I felt I should get what I paid for. Silence. The. He told me he had “upgraded” me. “For the kids though. If it was for you I would give you ZERO.” As he makes an O with his hand. I thanked him. Our room was not an upgrade and looked at a tree and the die of the building. My 9 yo made a comment that “that man was really mean. Why did he call you a loser?” Interrupte"

"Nice quick stay"

"Check in and check out super easy! Liked that I was able to do a check in online and able to add a late check out. Super convenient."

"What made the stay was the staff. So wonderful, from the front desk person to those working around the hotel. Good location. Clean property. Room was a little small but good for me, my daughter and her baby. Lots of stuff around. "

"Awesome place to stay"

"Tentative staff"
