葛瑞斯設有游泳池的飯店，旅行前必看！

"Everything in the room are old or broken or both. The soundproofing the very poor as well, you can hear everything happening outside the corridor. And there are furnishing noises at 8am. "

"I don't like the cleaner to clean my room at around 430 pm on 2 days. Hotel replied that they have more than 1000 rooms and will be arranged to clean some room on pm sessions. But I am satisfied with their reply as 4 star hotels should arrange staff to clean the rooms with efficient way."

"They were able to check me in early, at noon rather than having to come back in the evening. My single room was way roomier than I imagined, clean and tidy. They also have a programme where they give you a bit of credit towards the bar or restaurant if you opt to skip housekeeping. The hotel is situated at a very convenient location, supermarket across the street, and tons of food options all around. All the major central London landmarks are within half an hour of walking distance, even Tate Modern."

"The front desk were polite and thecleaning staffs were professional. Eating are not convenient as there is only one restaurant in the hotel and those near by were pack up with tourists."
