We stayed 1 night in the 4-poster room. Incredible location with amazing view of Loch Long from the window. Short drive from Glasgow but a remote west coast feel, and it's a beautiful drive to get there.
The room itself was luxurious and olde-worlde. Big airy bathroom, huge 4 poster bed and comfy chairs by the window (just down the loch from Faslane so you, like us, might get a close-up view of a passing submarine...!)
We ate in the restaurant. The food was very good. However the vegan options were not great; none listed on the menu, the kitchen made a vegan option (we had informed them in advance of our vegan diner) but the 'main course' of roasted veg was like a side dish missing a centrepiece. The same has to be said for the room where e.g. some oat milk with the tea making stuff would have been appreciated. Not the worst for vegans by any means but does feel like this hotel hasn't quite caught up. After the meal we had coffee by the fire in the lounge which is cosy, warm and lovely.
Unfortunately the next morning the hotel had a water issue as the whole area lost water so we couldn't shower or flush and breakfast options were limited. Breakfast is VERY expensive at £18 per head for the sort of standard offering that is included at many hotels. The water issue wasn't the hotel's fault, and staff were lovely (though v stressed!) but I was surprised not to be offered a discount, at least on breakfast, as apology.
Overall a lovely stay but with a few issues
