Piscine Armand Massard

Both pools were in use for lap swimming when I went, but the lanes were not speed or stroke designated. Most of the slower swimmers were in the smaller pool. There were six or seven swimmers per lane in the 33m pool, so it was a bit crowded and there was quite a bit of passing going on. The pool was open only two hours today (Monday), which might have contributed to the crowding.

The pool has electronic-coded lockers, large locker rooms with small changing rooms; all facilities are unisex. The pool and facilities were all clean and the staff was helpful.

The water was immaculate, clean as could be. I'll be back.

I'm not sure what the bad reviews are for. The pool was very clean - I could see to the other end - and it was deep enough for diving into the lane. There was the usual chaos with slow v. fast swimmers in the lanes, but there is room to pass. The showers and lockers are old, but clean (you don't need to bring a lock); it's in a central location; has good hours; and is cheap.

When I went, this pool was clean and not too hot. Both pools were open. On a weekday, the pools were busy at opening time (7 AM) but much less so on Saturday.

I didn't find this pool filthy. The water was way too hot (86º - 87ºF.) and because the 33m pool was closed, the 25m pool was crowded. Doing laps was like an obstacle course. The air inside was a bit close; it smelled like fresh caulk. The staff was unhelpful. They assured me they would be open on Sunday, but it was (surprise!) closed. They did post listings for other pools, and I went to one.

The strangest pool underneath the Montparnasse tower; cold 60s architecture and quite filthy.
