The Edinburgh Carlton was the first hotel to have a lounge, so I trotted down there expecting to be wowed by a sumptuous array of canapés and drinks. Oh dear. Having been assured at reception that my room key was set up for lounge access, turns out it wasn't. Embarrassing to get a big red light and beeping noise at the door and slightly annoying to have to go back to reception. For the fourth time.
Here is the lounge after it had cleared out a bit. When I finally managed to get in, there was one table free, surrounded by a generous amount of crumbs, so at least that reminded me of QF's J lounge at SYD dom and made me feel right at home

It was not a big lounge but nice enough. There was some blue cheese (there had obviously been other cheeses too earlier, judging from the smears on the platter), no fruit left, some yogurts, some chocolate bars, some biscuits and oatcakes but the best thing was some hot salmon with sugar snap peas and cherry tomatoes. There were spirits, beers, white wines in the fridge and the red wines on the shelf which appeared to be unopened. I decided to have an alcohol free day, but I enjoyed the salmon and the unexpected but welcome chance to eat some vegetables with it.
Back in my room, the clock had not been changed for daylight saving. But at least this clock had a manually operated screw, unlike the Aberdeen Garden Inn where it needed a screwdriver to be able to get to the settings switch. So I fixed the clock myself. Kind of sloppy that the hotel hadn't bothered, frankly. They'd had 4 days to get round to it. (Did I mention the second Doubletree I stayed at didn't have a clock at all?)
No bathrobe, no cotton buds, but a shower cap, notepad and pen were in the room, and a liberal quantity of chocolates (yum!) and a welcome letter. Sorry no photo of the chocs

Can't think where they went. No bottles of water or discount voucher for the hotel restaurant. Proper soap, not liquid dispensers.
Being a hotel in a really old building, there were some quirks like squeaky floorboards, sloping floors and weird steps in the corridors (4 steps down then later 5 steps up in the corridor to my room, difficult with bags when I left but the porter Nick was really cute). On the whole I was pleased with the room and the (narrow) view of Arthur's Seat.
All the other hotels had all-Twinings teabags in the room. This one had Twinings except for the everyday black tea which was Tetleys. No biggie just a noticeable difference.
Housekeeping came the next day while I was out and for some reason did not wash the used cups or glasses although they did everything else that would be expected. They also managed to leave the floor messier than before with little shreds of paper on it that hadn't been there when I went out.
I was told I was entitled to breakfast in either the lounge or the restaurant but didn't bother. By the size of the lounge I'm guessing breakfast would be a zoo in there.
The second night I went to the lounge again. There were someone's 2 feral kids running amok, opening the fridge doors and leaving them open and pushing in front of people at the food displays. There were no clean tables so I walked out. The bar menu was unappealing with all high-salt, high-fat heavy dishes and I just felt like a snack. So I went back to the lounge later and the brats had gone thank goodness but still the same dirty plates and glasses on most tables that had been there the first time. I found a clean table and the evening's hot dish was party pies with baby carrots. It was nicer than it sounds. There was some fruit left this time too. I didn't try the alcohol as I'd already had a glass of wine with a cousin.
How I feel about this lounge is - meh. I wouldn't be rushing back to this hotel for its lounge, despite the vegetables
How do I feel about Diamond at this hotel? The receptionists all acknowledged that I had diamond, and I got a king size bed having booked a queen, but getting a king size bed happens quite often in hotels even when you don't have supposedly high status and Diamond didn't get me my room ready on arrival. Yes I got lounge access this time. I could have paid for that if it was vital to me, without needing to maintain status to get in. So all in all I'm giving Diamond a score of 2 for this hotel, mainly for the chocolates
