The apartment was located in a very convenient part of Budapest -- basically, right on the Danube and a block or two away from one of the bridges to cross the river. The unit is situated in a courtyard so was very quiet. The only "issue" I had was in the evening when I was sitting at the kitchen table on my iPad, the door opened and 2 guys in their 20s were there, obviously at the wrong unit. I just hadn't locked the door fully, but that was a bit weird.
Also, I liked that the apartment had a full kitchen and the host provided coffee and cereal, which was appreciated.
