You see these stores that are called "дом быта" all over town, and for non Russians it can be quite unclear what they are about. These are super convenient stores where you can have your passport photo's taken, zippers fixed, clothing&shoes fixed and cleaned and keys duplicated.
You can simply type in "Дом быта" in your Yandex.Maps app and a lot of options are likely to be shown up. A value of speaking Russian cannot be underrated for running these kind of chores.
