Location - very clean - staff

We couldn't see the park or the outside because the window in our park-view room was dirty; the furniture quality in the rooms is at hostel level.

Breakfast217Mostly good
The breakfast in the club was very nice.

What a wonderful hotel with one of the best Marriott lounge breakfasts that I’ve ever had.
Google, September 2026, rated 5/5 by this guest
The breakfast is à la carte, that means that you will only have the right to have one (a unit) of bread, a coup of coffee, some juice and an item in the menu.

Beds94Mostly good
The bed is soft and comfortable, and the location is great — within walking distance to Hyde Park and Oxford Street for shopping.

The breakfast / dining area needs a revamp as it’s looking tired with chipped furniture etc.

Tired decor & poor room design
Booking network, July 2026, rated 6/10 by this guest
Firstly, I disagree with the whole other posts saying ‘the room is too small’ it’s not - it’s an older hotel thus the rooms are pretty big.

Value212Weak spot
Not a good value stay in the area, falls short of other local hotels
Tripadvisor, January 2025, rated 1/5 by this guest
The staff, food and area were all excellent but the rooms are looking quite threadbare and for a room that has had no refurbishment since the last time I stayed there, the cost had tripled.
Booking network, January 2025, rated 7/10 by this guest
the room and the toilet like 4 star not in the stander of 5 star and the value of money

A thief could easily break into your room due to the lack of security.

Two bags were stolen from the property, which clearly shows a lack of proper security and protection for guests’ belongings.

Upon arrival, however, I was informed by Mamun at the front desk that while my room was supposedly "ready", I would instead be given a temporary and smaller room for a few hours while the air conditioning in my assigned room was being repaired.
