Everything was top notch. We were there during a heatwave of 3 straight days of 102+ temperatures and the A/C struggled to keep up but pretty understandable. Paris isn’t built to get that hot, so you can’t hold that against Les Bains. Other than that, we greatly enjoyed our stay. The location of being in the Haute Marais was also a great perk. Literally walkable to any of the major spot, other than the Eiffel Tower, but it’s also located only a few minutes to the Metro 3 and also a few minutes walk to the Metro 4 stations. Fantastic location.
