I have no experience of the GEH prior to the recent renovations; and I do not wish to appear as an advocate of this property - other than to say I was impressed with the new ANDAZ™ concept of staffing, attitude and inclusive services.
Just for the record. the various rooms types are as follows:
City Single 25 sq m
Queen/Double 27 sq m
King/Double 29 sq m
King Studio 32 sq m
