    Such a beautiful hotel in the heart of London. You can go to so many places on foot from here. The room was beautiful and very clean, the service was amazing and the staff are super friendly and forthcoming. And I can only recommend the M Club lounge downstairs, there's always snacks and drinks for you to take at any hour of the day and the breakfast buffet was super good. One of the waiters, Maxim, even took the time to talk to us for a bit. I can only highly recommend this hotel!

    Spent 6 nights here recently and loved it! The neighborhood in which it lies is fantastic, amenities are good (what you would expect), restaurants are VERY good, staff is TOP NOTCH! They wait on you hand-and-foot, and Albert in particular was incredibly helpful and resolved a lost item issue almost immediately. It is an affordable hotel in a posh location and the restaurants/bars around it are great. You will not be disappointed with your stay here.

    Albeit in the middle of renovations this is a 3 star hotel with a doorman masquerading as a 5 star. Rooms are small, breakfast and lounge are average, and all the staff need to smile more. The buffets are not replenished unless you ask. They also have a propensity to try to take away plates and cups before you are finished. Location is a huge advantage and rooms are quiet despite the outside traffic but you get the feeling they are resting on these laurels.

    Seriously, the kitchen smelled in my room twice a day. at morning and at 5 pm everyday. I couldn’t understand why it would be in room and corridor. Don’t be expect to be appreciated as Platinum Marriott Bonvoy. The good thing you have access to M lounge and this is normal The location is amazing Staff and room service are excellent and great One other point need to improve; they didn’t respond to phone call mostly from room 🫠 From my point of view; it’s not a great value for what I paid I would consider this hotel as 4 star hotel not 5 Again, small details could destroy your comfort 👎🏻
