Vilnius Old Town () with medieval stone paved streets and Užupis offers one of the most prestigious housing in Vilnius. Many old town apartment buildings there offers direct views to the iconic churches or the biggest landmarks of the city (e.g. especially desired Gediminas Tower), enclosed inner courtyards, high ceilings, attics, non-standard layouts and luxurious historic interiors. Most expensive flats in these neighbourhoods may cost millions of euros and are accessible only to the wealthiest residents of the city. However, such problems as traffic jams, expensive car parking spaces, air pollution, high costs of maintenance, limitations for reconstructions repels rich Vilnians from living in these neighbourhoods, who often buy or build private houses in more distant parts of Vilnius (Balsiai, Bajorai, Pavilnys, Kalnėnai, Pilaitė and others) or nearby areas of the Vilnius District Municipality. About 21,000 residents live in the old town and 7,000 in Užupis.
