  I smelled strong vapors like Raid Roach spray and chemicals in my room it disturbed my entire night’s rest causing me to be disoriented by the fumes. The AC wasn’t helping either I think it was clogged with dust and grime. The sink also would backup with water and not drain properly.

  I have yet to even complete my stay at this location, but I’m already leaving this review because my interaction with the front desk staff this morning was the final straw. I am a Best Western Platinum member, and Best Western has always been my first choice hotel chain. I have stayed at many Best Western locations and have had positive experiences, which is why this stay has been especially disappointing. This location appears to have invested a significant amount of money into upgrades intended to make the rooms "look" nice, but the underlying condition of the property still feels extremely rundown. Just to name some issues, my room had a broken toilet seat, an unkept shower, doors that are visibly worn and in need of attention, along with front door seal is terrible you can see light come through which likely means pests can also sneak in. Also, all the light switches are backwards and the fan and light in the bathroom are connected to one switch even though there is clearly two switches in the bathroom, one just does nothing. This is also the first Best Western where I felt like I needed to photograph every mark, scratch, or imperfection the moment I entered the room because I was concerned that I might not receive my deposit back. That is not the kind of experience I expect from a hotel chain I have consistently trusted. The breakfast policy they have is also ridiculous. The dining area is far too small to reasonably require guests to remain inside to eat. I also found it extremely uncomfortable to have a "security guard" monitoring guests and telling them they could not leave with their breakfast, with a $20 fee being threatened if they did. As for the final straw I referenced above, I requested a late checkout, something I have done at other Best Western locations without an issue, and was told that the latest they could extend my checkout was 11:30AM. I have never experienced this at any other Best Western location. As a Platinum member who has stayed loyal to this brand, I found this particularly disappointing. I understand that late checkout is subject to availability and hotel policies, but the experience and lack of flexibility at this location were very different from what I have come to expect as a Best Western guest. To be honest, I completely regret using my free night stay at this particular location. Had this been my first experience with Best Western, I would never have become the loyal patron I am today.

  Worst best western hotel I ever lived in. I accidentally selected one adult for a two queen bed room but we actually have two adults so we were charged 50% extra fee? Although the price for one or two adults is the same for this room. The room door can’t close automatically when you leave, and you need to push a bit. The breakfast is so bad, not as good as SureStay. Most ridiculous is I wanted to take one plate of food for my partner and the staff denied.

  The hotel is decent for what you are paying. The only big problem that this hotel is one staff member he is really rude and don't have any type of ethic. On night I was washing my clothes in the hotel laundry room, and the laundry room doesn't have a close time sheet on the door, but he got there and make me take my clothes out the laundry because he said the laundry room close at 9PM he didn't even let me finish washing my clothes that was almost donde. Another time more recently I had to leave the hotel early due to an emergency and call front desk that I was going to be getting a package at that direction and if they could give the packages to my roommate is not the first time, we do it like that and this time a staff member really rude refuses to give my roommate the packages that I needed and on another occasion the hotel miss to clean our room and needed towels to take a shower that same staff member he only give me one towel and requested more due that I was sharing my room with a roommate and he refused, saying that it might be are fault the lady direct when to clean are room due to us.

  I am extremely disappointed with my recent stay at Best Western Diamond Bar Hotel & Suites. Upon entering my room, I discovered that the bed sheets had clearly not been changed after the previous guest checked out. There were numerous body hairs all over the bed, making it obvious that the bedding had not been cleaned. This was extremely disgusting and completely unacceptable. I immediately reported the issue to the front desk. Unfortunately, instead of apologizing and resolving the problem professionally, the front desk manager displayed an extremely rude and dismissive attitude. There was no sincere apology, no concern for guest hygiene, and no effort to make the situation right. As a hotel guest, I expect at the very minimum a clean and sanitary room. Sleeping on bedding that appears to have been used by another guest is a serious housekeeping failure and raises significant concerns about the hotel's cleanliness standards. I request that Best Western Corporate investigate this incident thoroughly. I also expect an appropriate explanation, corrective action, and compensation for such an unacceptable experience. I have taken photos as evidence and am prepared to provide them if needed. I sincerely hope Best Western takes this complaint seriously, as this experience has severely damaged my confidence in your brand.
