This cozy 28m² one-bedroom apartment is wonderfully located in the heart of the 5th district (the most central district of the city). You will be 5 minutes away by foot from the famous St. Stephen's Basilika and Andrássy avenue (the Hungarian "Champs Elysées”), the Danube and the Chain Bridge are 1 block away, the famous Vörösmarty Square (where the Christmas market takes place) is around the corner of the building, and the Buda Castle is a 10 minute walk. This is the best location you could possibly get in Budapest. The flat is in the same building as Dorottya Apartments 2 and 3.
