Gyms in Paris with day passes?
I live in Ireland but I often stay in Paris for a week or so every 2 months. I'd only want to use a gym in Paris around 15 days a year, so it's not worth subcribing for a long period. Are there any gyms where I can pay just €10 or €15 for a day, without a contract? An AI suggests Basic-Fit but I can't find any mention of day passes on their website.
Edit: I see that both Basic-Fit and easyGym have carnet-type offers for just €10 a visit. Anyone with experience of these gyms? Are they crowded? Is their equipment good? Any other information?
