Maybe I should start with the good stuff: The people working at Piscine Guy Bey were very friendly when I was there. On a sunny day like the day that I was there, the pool hall is suffused with light. The one and only basin is 50 Meters long. The sun-deck is quite nice despite just being a big concrete balcony. If you discount grime, it was quite clean when I was there.
If you don´t discount grime, you will see everywhere that Piscine Guy Bey isn't quite up to modern standards. But nothing quite demonstrates what is wrong at this public swimming pool than the ceiling in the pool hall.
The acoustic panels that they´ve put under the ceiling (in order to reduce Indoor Swimming Pool Noise) have started to fall down one after another. So they´ve installed a net underneath them where they are now agglomerating - and it is quite a number of those (not exactly small) panels. Also, with those panels coming down in masses, I´m wondering how much this net can hold until it itself is coming down. Also, are they now just waiting for all the panels to come down before fixing the actual issue here (panels falling down for some reason)? It is something that needs to be fixed, the net just (hopefully) keeps your customers out of harms way, it doesn't fix the actual issue here.
Another thing that I found negative - this may be one pool that has too much activities on offer. Between Aqua cycling, Aqua Power, Aqua Fitness, Aqua Slim, Aqua Stretch and the local swimming club taking up a lane or two - you will find it hard to actually use the 50 Meters of length this pool offers on paper. You really need to study their agenda carefully before going there if you want to get some swimming done.
Practical Info: RER Station Meudon-Val-Fleury (RER C) is not far away, but it is a steep climb to get to pool from there. There are Plenty of parking-spaces in front of the pool. Bathing-caps are not mandatory in this pool. Lockers need a 1€ piece. The Floor is quite slippery in the pool hall - bring sandals/flip-flops. read more
