"We had a very comfortable, clean, spacious room overlooking the Millenium Bridge. We needed to be quiet, as we were attending a family funeral. And it was.
The facilities in the room are excellent. You have everything you need and more.
Watch out for extemely hot water in the shower.
Also, we paid an extortionate amount of money for a 10/15 minute taxi ride which the hotel booked for us. I would suggest booking an Uber or Google a local company.
Lastly, the food is delicious, but we thought quite expensive (there is a Prix Fixe menu). Our breakfast was included in our room rate, so was cost effective and excellent. We will definitely revisit Malmaison and do recommend. "
