Reflection in a swimming pool

A month ago we spent a long weekend in Eger (North Hungary) in a nice hotel. Original it was built for a single family, with a lot of luxury items before it became a hotel. I've shared some photos of a fancy bathroom in it, now here are some shots from its wellness unit. There are a jacuzzi, sauna, solarium, and my main subject, a 10m-long swimming pool...

I switched my smartphone in Pro mode on a selfie stick that can be turned into a tripod (Huawei AF15) in order to take long exposure photos.
