The property is clean and in a good, walkable neighborhood for many things. The staff is professional and helpful. The rooms are very small but clean. Also, they say they have king-sized beds, but they are the size of a standard Queen. In the US and other Places in Europe, a King is a King, however, at the Mercure Hyde Park, a King is a Queen, and to actually get a King, you have to upgrade, and it's not one bed. Its two twin beds are pushed together, trying desperately to make a proper king. I was told by the staff this is the way it is in Europe, however, I'd just come from Iceland, and clearly, they understand a king bed is a king bed. Again, it appears that Mercure has its own standard, and that is not effectively relayed on their website when booking; therefore, I feel it's misleading. The trash along the sidewalks for days is also a bit gross. The breakfast was decent and easy each day.
