Just wrapping up a 5 night stay here using a Cat 6 cert. I have no major complaints - the service both in F&B and front desk/concierge has been great. As Golds we were 'upgraded' to the Sky floor which basically means a bigger room on the 16th floor. It was comfortable and roomy enough for two of us for the week. I guess the one downside if there is one is that it's a busy hotel...there was a conference or two here and so the lobby and restaurant/cafe was always pretty busy.
The location is a few min walk from Old St Tube station which was convenient. There's also tons of restaurants and cafes within walking distance and even a self serve laundromat 10 min walk away (which we availed ourselves of!).
Didn't get any free breakfast or anything else being a Gold but used the lobby cafe every morning for and had coffee and scrambled eggs (around 10 GBP for both).
That's about it - any other questions, let me know!
