For my tastes, this is one of the prettiest modernist homes in Reus, and it’s located in downtown in Plaza de Mercadal, the same one as the Town Hall. It was built by the architect Domènech i Montaner.
On the ground floor, there’s a bakery/candy shop that belongs to the descendants of the original owners. The home has tons of details, but to visit the inside you need to reserve a visit through the Tourism Office. It’s worth it to pass by, even if to just admire it from the outside.
