JW London Grosvenor House

"My husband and I have been going to Park Room for over 6 years. This place never fails to impress us. We went there for my birthday last week and had a great time. We were served by Altay and Pratiya. They were both extremely nice and professional. We have been served by Altay previously but it was our first time being served by Pratiya. Been told she is new but wouldn’t be able to tell as she did her job so well. highly recommended and will come again."

"Our stay at the JW Marriott Grosvenor House was excellent. The newly renovated 8th‑floor king room was beautifully done, and the Executive Lounge offered plentiful food and beverages. We were very happy with our visit and look forward to returning."

"This is a tough hotel to rate and here's why. The rooms are clean and well appointed, but not sound proof enough due to the guests who stay here. We arrived to find the courtyard full of exotic cars: lamborghinis, G wagons, GT3s etc. We thought maybe an exotic car show was going on at the hotel. It wasn't an exotic car show at all. These were the cars of the guests WHO LIVE AT THE HOTEL. More on the problem with the soundproofing later... Check in was smooth and the staff welcoming and polite. The location is good as it's walkable to many attractions within a 20 - 30 minute walk. The problem was the other guests and the staff's seeming inability to do anything about it. I understand that hotels cater to guests of many nationalities, cultures, and practices, however, common courtesy should be upheld despite your culture. I was invisible. The men of the predominant culture would push past me to get in and out of the elevators as if I didn't exist. And when I say predominant, I mean the lobby looked like an embassy. Okay, so you have no respect for women, but then, at midnight, the guests with the thunderous cars would go to the courtyard, idle their engines, rev them a lot, and then finally squeal off into the night. This is unacceptable behavior no matter where you come from. The next morning, we complained to the front desk clerk who disappeared into the back room for at least 10 minutes and then came out and said there was no room they could move us to. This is an enormous hotel. I find it very difficult to believe that there was no room further away from the courtyard to move us to. Rather than have a policy prohibiting idling in the courtyard after 10pm, or speak with their guests with the loud cars, they chose the path of least resistance, simply tell the American guest at the American hotel, "no". They were polite, but the answer was still no. I guess the Marriott isn't going to mess with their bread and butter guests who live there. When I'm a guest in a foreign land, I gladly adapt to the acceptable customs (like wearing modest clothing and a head covering at the Blue Mosque), but when foreigners travel to western lands, they get to do whatever they want? That is not acceptable. Western courtesies of allowing ladies to go first and maintaining quiet time after 10pm are what I expect in a western hotel. That said, unless you're a night owl and love the sound of revving engines at midnight and enjoy getting shoved past in the elevator by rude men, avoid the JW Marriott Grosvenor House like the plague. Worst nights stay ever at a luxury hotel. Not Western or American friendly."
