Great hotel in a fantastic location, a stone's throw away from the Millennium Bridge. Our stay was very enjoyable overall.
The Locke opened in March, then took a hiatus as the country went into lockdown. And that newness shows: the room and all appliances were practically spotless. The rooms are stylish, minimalistic, and very smartly designed, packing in as many useful appliances and items as possible (ironing board, heated towel rack, stove top, etc.) given the fairly small space. The walk-in shower was great - a bit clogged initially, but management fixed that shortly after we raised it. We weren't sure where to put out our trash bags at first, but the staff clarified that they just go into the hallway for collection.
Everyone at the reception desk was very warm and friendly. That said, I'd recommend enforcing the current mask policy a little better for guests and staff. There were a lot of people walking around the reception area and other common areas with no mask on despite the government guidance on wearing masks in enclosed spaces. The (very helpful) staff member who refilled the body wash in our bathroom when we asked also wasn't wearing one. I know it takes time for everyone to get used to the regulations, but making sure people observe them will increase everyone's safety and security.
All things considered, still definitely a five-star stay, with warmth, hospitality, great value, and a young and vibrant vibe all around.
