A few points from my recent stay, my first since 2019:

Upgraded from basic room to 1-bed suite (Plat member here). AC units were in the room but not yet operational - signs around the hotel say that fitting is continuing and they will all be operational when the installation is complete. In the suites there will be AC units in both the bedroom and living room. Guessing there will be remote controls for operation which they're not putting in the rooms yet. The room I was in was in good condition, clean and the kitchen was reasonably stocked with cutlery and crockery. There were two induction rings in my room so perfectly fine for your own cooking with a Sainsbury's Local around the corner.

Breakfast is fine, the website says continental but there are hot items - bacon, sausages, scrambled egg, beans, porridge. Quality is not great on any breakfast item but will be enough to fill you up before your day. The breakfast room gets packed at the end of breakfast, with no free tables. The buffet is cleared on the dot of 10 weekdays/11 weekends so I wouldn't leave it too late - I guess given there are kitchens in the rooms they may be relaxed about people taking stuff back to rooms if the breakfast area is full.

The nearby parking no longer has any arrangement with the hotel, so if you don't prebook then you're paying the £26/day full rate. Prebooking via q-park.co.uk might give a discount, but it's demand-based pricing so trying the day before gave me the offer of a discount of precisely 61p for my three-night stay! Picking random dates in the future suggested you might be able to get a few quid off but city centre parking is never going to be cheap. There are a lot more spaces in the car park reserved for office tenants, so I guess q-park no longer need the hotel business.

All in all a decent stay - pricey (£841 for three nights, booked in the recent Sale), but hotel prices in Edinburgh have gone up significantly post-pandemic. I like the location and the extra space (even in the regular rooms) is welcome.
