Very Disappointed with the Ritz in San Francisco
I stayed at the Ritz recently at a reduced rate. The welcome was very good at the curb but when I checked in at the front desk and they saw what a good rate I received, the front desk clerk was a little rude. When I got to my floor I was taken aback at how dirty the hallway rugs were. I talked to the front desk and they explained that they were preparing to replaced the rugs but I noticed the same complained almost 4 months ago by another trip advisor reviewer.It does not cost a lot of money to steam clean the rugs. 
I am a Platinum member with Marriott and I asked where the concierge lounge was and was told that even though I was a Platinum and that the Ritz is now part of the Marriott chain that I was not allowed in the lounge. However, that did not make sense since I have use the Ritz lounge in other cities being a Platinum Member. 
On the positive side the hotel has a very good gym. 
My recommendation is to stay somewhere else. The St Francis , Westin, Hyatt, the JW, The Union Square Marriott or the Renaissance on Nob Hill definitely know what customer service is and how to create a welcoming atmosphere. Thumbs down on this Ritz. I will never stay here again.
It is a shame. Usually the Ritz is exceptional.
