Just got back from a half-term stay at the Radisson Blu and we're really pleased we went. We had a two bedroom suite (actually, we got upgraded to the 3 bedroom - it's absolutely vast! But the experience between the two is common, so still relevant).
The beds are comfy - really soft but comfy, although the feather pillows go to nothing. You can get different types from reception but we ultimately didn't find any of them particularly good. However we're a bit fussy when it comes to that so I can't blame that one on the hotel at all.
Every bedroom has a bathroom, and he bathrooms are generous! The lounge and kitchen area are a boon, and you can cast to the TV's (in theory, it uses Chromecast but it didn't work for me unfortunately, I also don't know if it would work with an iPhone).
The balcony is where it's at though, it's huge, even on the two bedroom one it's massive and it is such a big perk! Ignoring the hot-tub (which you fill fresh each time you use it, which is nice), the table and chairs sun lounger make it a real escape!
