I'm very picky about cleanliness in hotels. If I'm spending over a hundred quid, I expect cleanliness and comfort above all, then location, friendliness, lobby, etc. The room and bathroom were spotlessly presented, everything worked, the bed was comfy and it was quiet (I always request a quiet room, as a veteran of London hotels, knowing that there's a lot of noisy things in the city, roads, trains, tubes, clubs, etc).
OK, so it's a London hotel, rooms are always tiny and indeed mine #206 was small, big enough for a 4'6" bed and a gap enough to walk round either side. There wasn't space to put out a laptop to work, although there was a chair, open face hanging rail, safe, etc. It was a double room, but if there were two of us sharing, especially if it was rainy out, I'd have felt cramped - but it was just me, and it was fine for me.
Bathroom, whilst naturally compact, had a fabulous shower, heated towels, etc. Again, spotless, and that's most important of all for me.
The street entrance doesn't do the rooms justice, a staircase nestled between two shops, but once you're in, it's comfortable. There's one public area for reception, bar, breakfast, lounge, and it's attentively maintained. Breakfast was continental style and was pretty good, topped up, wide choice of teas and styles of coffee. There was an optional upgrade to a cooked breakfast, but there are cheaper places just outside which may cater cheaper. The dining space can fill up at breakfast time, so ask reception what's a good time to dine. At 8:30 there was space (business travellers have left for work, leisure still in bed), by 9 it was full, and I imagine it empties out again towards 10.
Location is splendid - you're just across from the park and once inside you're with the birds and trees, short walk to RAH, Kensington Palace, etc.
My meetings were all around High St Ken, so perfect for me. I will stay again for leisure and meetings, but will go somewhere larger if I need a desk to work from. less
