“Ok for a quick stop but that’s all.”
+I liked the lime bar as it was adult only. That was it really. Room was quiet view was nice. But other rooms could see in.
−Breakfast was very poor. Fake juices, flavourless sausages. Eggs saved it. Pool was small, and cold. Could not get a seat in sauna. Room was cold, huge draught from windows. Cocktails weren’t nice in bar. No water on landing. No toiletries just a shower cap x 1

“we enjoyed ourselves lovely stay”
+very clean and very warm
−I didn’t know how to put the heating on in my room but that might’ve been just cause I didn’t know not that there wasn’t any option and just the times to go in the pool for the baby is at 10 and quite difficult to get ready and hold the baby at the same time

“Excellent four-day stay stay with an unpleasant last 30 minutes”
+There is a wonderful atmosphere in the main hall, where folks have coffee and pastry and just sit to to talk. Wonderful place to sit and talk. Most of the employees were awesomely kind (with one exception mentioned elsewhere) Very comfortable bedroom; nice coffee bar and very nice middle-brow restaurant (never looked inside their luxury dining)
−Checkout was very unpleasant: I showed up a little after 12 noon, checkout time, believing someone else my room had gotten a half-hour's extension (she had done so with the cleaning crew, but not with the front desk). When my card no longer worked to get into the room, I asked for another card. She replied yes, but I would be billed for another night, and that there was nothing that could be done in consideration of the needs of the cleanup crew. Apparently, she changed her mind, because after I rushed upstairs, removed my luggage and went back to the checkout desk, another employee behind the checkout desk said that there was no additional charge. I would be grateful not to be penalized for late return had the first employee not talked in such a mean-spirited manner. Also, the corner shower in our bedroom was rather narrow, and adjusting the temperature was a tricky proposition. We decided to use the very luxurious bathtub, with its hand-held faucet. That worked well, but an amply sized regular shower would have been even better.
