This is a solid option for a hotel pool, although the water is very warm and the 20-meter length is a compromise. They reserve one of the three lanes for aqua-walking, if someone wishes to do that. If that lane is empty, you may swim there. There are no backstroke flags, but they do have kickboards and pull buoys. Towels, shampoo, conditioner, and soap are available, which is nice, although you have that in your hotel room also, assuming you are a guest there.
