What do expats find most challenging?

"Expats in San Sebastian may find it challenging to adjust to the slower pace of life in the city. The local culture is very relaxed and laid-back, and it can be difficult for those used to a more fast-paced lifestyle to adjust. Additionally, the language barrier can be a challenge for expats, as Spanish is the primary language spoken in San Sebastian. Finally, the local cuisine can be a challenge for expats, as it is heavily based on seafood and other regional specialties," remarked another expat in San Sebastian, Spain.
