Water was probably in the low 70s. Def not high 70s. My one concern is the glass that holds the outdoor pool facing the city landscape. If you lean against it and look sidways, you can clearly see the curvature of the glass even though it's a good near 2in thick IIRC. There appears to be a some separation at the bottom where the silicon seal meets. I hope they perform an annual stress test on this piece otherwise it could be quite the spectacle during summer busy months.

Was offered indoor pool $35 for an hour for non-status members.

Btw if you're serious about swimming, Piscines Municipals Montjuïc is nearby though only open during summer season. Looks amazing.
