Cuenca doesn’t really have condo complexes or pools. Mainly stand-alone mid rise buildings. You’ll find many more pools on the coast where it’s warmer.
You will find some of the newer condo buildings in Quito have swimming pools. You can also get a membership to use the pools in Quito at Hotel Quito, Marriott, and Swissotel. There is an indoor community pool in Cotacachi but I understand the water is VERY cold.
