We enjoyed a very happy meet up with old American colleagues …a repeat of three years ago.

8.0

Check in was good. Location was good and facilities met with expectations.

Perhaps housekeeping took more notice of details like brass plates on corridor doors! General appearance of hallways and corridors look a bit tired…just saying!

The only good thing about this hotel is the location

This hotel is extremely old and outdated. The room furniture is outdated and dirty, the carpets are dirty, and the windows are dirty. The overall cleaning and servicing are very poor. I hope that the hotel will be refurbished to the standards of Marriott Hotels in the future.
