I normally stay at the Holiday Inn Express but gave it a try on this occasion.
First of all, I was not entirely sure if my Concierge status was recognised. This was probably due to an early checkin, but I do not think my room was upgraded. In addition, I was a solo traveller, my room was a twin single room...
The Concierge status gave you complimentary continental breakfast, however, most hotels allow such members to have full breakfast. However, this particular hotel strictly gives you continental breakfast only, which is not particularly worth. Moreover, this benefit was initially not recognised on checkin.
Room cleanness was questionable. Some croissant flakes were left on the desk. I also found the back of bathmat mat horribly mouldy, I could not touch it. I had never seen such a dirty bathmat before.
Considering higher rates, I will switch back to the Holiday Inn Express.
