We visited Budapest as a day trip by train from Vienna, which is nearly 3 hours in each direction. That left us only 6 hours to see Budapest. Andrea managed to give us an up close and personal look at the Jewish quarter of Budapest (including lunch at a wonderful restaurant called Carmel), as well as a great overview of the city through a combination of driving and walking segments of the tour. Andrea is very knowledgeable and willing to modify the tour as needed for each individual circumstance. We highly recommend her as the guide to use in Budapest.
