The room was beautiful, big , bed so comfortable!

Yuliya · AU · 2026-07-16

Location of room was nice but the staff and facilities made it difficult to enjoy establishment

2.0

The location of the room and its convenience to the city. Additionally, was grateful for the room service and them being able to attend to cleaning the room regularly from day 2 of stay.

Numerous things: • Bathroom was not attended to nor completed before my arrival of check-in. Evidenced by noticable dried-up feces or feral matter inside the toilet bowl AND behind the toilet paper roll. Thus, again, indicating no clean was conducted and no fresh toilet paper roll was replaced. • Prejudice to myself from front staff and discrimination of religious beliefs. Specifically, speaking with some staff members on some queries that were abrupt, irritated in nature, inconsistent prosody, and averting eye contact when approaching the front desk (i.e., am a man of tanned complexion). Additionally, requesting alcohol be removed from the bar of the room and to be replaced with water on religious grounds and this was not respected nor acknowledged. • Difficulty in enjoying stay with damaged air-con/ heating system. I had asked for assistance from staff on adjusting the program to have the heating system activated in the room (i.e., given the cold weather) and the functionality of the system was severely struggling; staff were unable to assist on the matter.

Very disappointing.

3.0

Coffee was good and hot and delivered quickly.

No room service, refurbishment prep already in place, mouldy grout in bathrooms. I wasn’t advised prior to my stay that they were about to close for renovations and thy at there was no room service
