Update on this after a recent stay, I was in the building with the reception, you do not need to go past reception just turn left when through the main door and free access to the lifts, so guests arriving own their own or if you are bringing someone back don't even get noticed.
Rooms are spacious beds are huge i was on the 14th floor over looking the pool area, Huge Glass window, safe in room, good shower plenty of hot/cold water and good power , location just off soi 11 is great no noticeable noise although i wasn't an early bedder so couldn't comment on noise levels between 10.00 & 03.00. Very Clean and tidy good room service, with buttons on inside to request room service or do not disturb no need to faf about with cards on door handles which some smart arse usually pulls of anyway thinking they are funny. Roof top bar is very nice, i didn't get down to the pool or use the Gym but both looked more that adequate for a short stay.
I would definitely stay here again only niggles to note -small lampshade low down above the middle of the bed headboard is a nuisance kept banging my head off it and the position/height of the towel rail in the bathroom is dangerous as i cut my head on it getting off the toilet (sober) and i am off average height.
