Plus points: Had a pleasant stay at Mercure Swansea. Room was big, bed was comfortable, whole place was very clean, and hotel was conveniently situated to get into city centre.
Minus points: My wife found that the hot water was not hot enough for her bath (though it was warm enough for me!). We were offered vouchers for breakfast for £12 when we arrived which we bought for 2 mornings of our stay but they weren’t great value. The receptionist said he “would give us £10 if we couldn’t find what we wanted on the breakfast menu- they had everything!”. This was a bold statement and I claim my tenner, as there was no porridge, no bananas and no croissants on the mornings when we had breakfast in the hotel. Which was disappointing frankly. I ended up having cereal and toast, and fruit juice and coffee. I’m pretty sure that would’ve cost less than £12 elsewhere.
