The hotel is in a good location. There are two/three tube stations within a couple of minutes walk. The reception staff are very welcoming and reception is warm and inviting.
However, the room I had was tiny. It's a sqaush and a squeeze to get to the toilet between the basin and the shower. To use the toilet (as a man) I had to straddle the pan rather than stand in front of it, otherwise the basin would have been in the way. Equally, if I had needed to sit on the pan, I would have head butted the basin.
I ordered the burger as a main and the cheese course as a desert. The burger was quite possibly the driest thing I've had to eat in quite some time. There was nothing enjoyable about it. The lack of moistness sucked all the flavour out of the burger, the bacon and the cheese. If I hadn't seen it I wouldn't have believed that either the bacon or the cheese was there (and I've just realsied that there was supposed to be a chilli mayo). The 'brioche bun' was also dry/stale.
The cheese course was a polar opposite to my bathroom experience. It was ridiculously enormous. There was about 150g of cheese, 10 crackers and some number of soggy leaves and mushy pickled walnuts. Not enjoyable in anyway.
C'mon Radisson, you can do better than this (I've stayed in some of your Scandinavian hotels). I know there will be a reply that says "i'm so glad you recognsied the warm and welcoming reception but I'm sorry you didn't have an enjoyable eating experience. Please reach out to us to.". However, people who read reviews realise that it is the experience of the guest that matters. It's not just that I had a bad experience. It's likely that it is like this all the time but the replies from the hotel will try to make it seem like it was a one off.
If you want a hotel in W1 that is mid/low price, and you don't mind small (and I mean small) rooms, and you intend to eat out, then consider staying here if you can get a cheap deal.
