We only stayed one night, and I was okay with the Adelphia - because I booked it - but my wife didn’t like it. It’s a little tired and in need of maintenance. To use the spa you have to ask at reception for bathrobes, then traipse thru the bar to get to the spa pools, swimming pool, and sauna/hammam. We didn’t see anybody use the changing rooms; they all seemed to change in their own rooms and walk through the hotel and bar in their bathrobes. Fortunately, there were no customers in the bar at 9:30pm on a Friday night! There is also no supply of towels for use in the pool and spa facilities - you just use the bathrobe. I used the spa pool and saunas - they’re a bit old but still function well; the changing rooms are a little tired, so I can see why nobody else used them - I showered in there after my saunas.
My wife didn’t like the level of cleanliness, and also felt that the bedlinen was a cotton mix rather than a decent cotton. Good location, but tired. Parking was secure and at no extra charge, so that was a plus point. We didn’t eat or drink in the hotel so cannot comment on the food.
