I offer you a very central yet quiet apartment next to Gozsdu court.
You reach every sights, shopping, bars and restaurants in minutes. Apartment faces to a small street, Szekely Mihaly utca that is located between famous Andrassy boulvard (high end boutiques) and popular Kiraly street (bars and restaurants). You cannot beat this location. You are in the middle of bustling city life but on the third floor (with elevator of course) so you can rest yourself at the same time.
