The travel site, airbnb recommends Szputnyik shop if you visit Budapest and would like to shop:
"Why does fashion need to be restricted by eras? Szputnyik really helps fashion lovers understand that both vintage and modern can exist in one cohesive setting. The brand is so successful that it has two locations in Budapest. This is perfect if you’re looking for one-of-a-kind piece, or something that creates a new look for the season or even if you’re on a budget. Both locations will offer something for everyone."
