Upon arrival, we asked the front desk staff to reserve a second night for us. We showed her the Hotels.com rate for this booking at $116. We asked her if she could match this offer... otherwise we would have used the Hotels.com website to book it (and would have changed rooms if need be in order to take advantage of the Hotels.com rate). She quoted us at $120 for the second night, based on this info. We took her at her word. Upon checkout, we were billed $166 for the second night (instead of the $120 quoted to us the day before).
Also, we asked for a taxi to take us to the metro station upon checkout. Just before the taxi arrived, the Hotel shuttle bus pulled up to take departing guests to the metro station-- for free. The staff who called the taxi could have easily (and therefore should have) mentioned their shuttle was arriving at that same time. This happened immediately after we were charged extra for the second night's stay. Notably, this was not a language barrier issue. We emailed the hotel's corporate offices to address these concerns- they still have not yet replied.
Also notably, the gift shop staff were very sweet.
