Katona Apartments in Budapest
Awesome place to stay in the city center. A block from the pedestrian area, a couple of blocks from the Danube, less than a block to a metro stop, a short walk to the Central Market. We had an apartment that would easily and comfortably sleep four, a private bathroom, a fully equipped kitchenette, a washer, and a table and chairs. The owner, Virag, met us at the entrance at our check-in time, took us upstairs and pointed out every feature of the apartment. Then she stayed with us for a good 15 minutes to tell us about the city and give us advice on where and how to see everything we wanted to see. We paid 147 euro (US$187) for three nights in mid-September.
