A lovely clean, comfortable and stylish room. Yes, you will need the earplugs provided due to it being opposite the main entrance to Waterloo station (note the underground exit brings you out on the higher storey!)
Rainfall shower, fluffy towels, decent sized fridge.
There's steps up to the rooms because it's an old building.
Breakfast selection was good, fresh pastries, cereals, fruit, cow and plant milk etc. And a selection of cooked breakfast to order.
The only slight feedback I have is that I requested the poached eggs to be fully cooked. I clarified that I meant "not soft". Unfortunately they came out soft poached. This isn't just a preference, people with compromised immune systems need to avoid certain foods being undercooked.
I didn't send the breakfast back because I didn't want to have to explain my reasons, but perhaps some training with your staff would help avoid this in the future.
Otherwise, a great place and I would certainly stay again.
