Pros (+) The staff was very helpful on arrival, with water, wine, and snacks, as well as information about Budapest. The location was quiet, but relatively central to Buda and the Metro. Very large apartment, with comfortable accomodations.
Cons (-) Typical challenges associated with being in a very old building. Small lift, and lost hot water briefly, as the boiler went out, but they were responsive to repair it in very few hours.
