A person can rent a number of items, such as refrigerators, baby carriages, TVs, coffee pots, furniture, bicycles and much more. Try the official rental stores in the nearest "rental point" (punkt prokata). Selection will vary from store to store. Note that a Russian passport must be presented for identification when renting from the old state owned bureaus. Ask a friend. There are dozens of rental points, here are only a few.
