It is too cold to be enjoyable and impossible to build up laps due to 20m. They appear to want to exclude the public with this policy. They need to wise up and up the temperature at least 4 degrees. Very disappointing.
The concept of this pool is a bit questionable. For a lap pool it's too small. 20 meters length is not fun for a serious lap session. However for any other recreational use it's terrible due to the freezing water temperature.
I hope they quickly come to reason and increase the temperature of water and air.
