I have been using this Mercure hotel for around 13 years for work and non work stays in London. It’s in a good location to get to where I want to go.
The hotel has been improved over the years and the staff never fail to be helpful and polite. And in general I find it a good hotel to stay at.
A plus point for me are the refillable water bottles in your room.
However, there are some small touches that seem an insignificant, can be tad irritating when not done e.g. only one glass in a room for 2, can’t get the TV to work and milk/coffee not refilled, plus after going down to the bar upon a late arrival for a ‘night cap’, to find the beer pumps are turned off at 11pm - no idea till you get to the bar.
That said Aussie sounding (sorry if not!) chap on reception was very helpful and sorted the glass, TV and milk, with no quibbles.
