My gym has quite fancy interiors. It used to be McFit but in 2017 it changed to John Reed. The renovation focused on artistic interiors. Quite a unique look and feel for a gym that costs 20 Euros a month. Some days they even have a DJ playing a live set.
I appreciate this interior style. Makes you feel like a member of a premium fitness studio. Chandelier’s everywhere and ceiling art like Leonardo Da Vinci. Only downside is weekday evenings are quite busy.
