My stay was brief but highly enjoyable. Staff were very warm and welcoming and the room was immaculate. I also got to use the sauna, which was a welcome bonus.
Just one small improvement would make a real difference: the bathroom had one of those terrible half-screened showers, which meant that water went everywhere. It's hard to relax in the shower when you're conscious of potentially flooding the place. A liquid soap dispenser (like the one in the shower) at the handbasin, rather than a small and slippery piece of soap, would also work well. White Company toiletries were delightful!
I highly recommend this hotel, it's a real find in central London.
