We took a 'free' walking tor round the Old Town and it was well worth it, even on a very hot day with the occasional rain shower...! The guides tell you up front that they work for free but appreciate tips so you know where you stand and, since that is their main source of income, fair enough. The young lady on our tour was friendly, knowledgeable and easy to understand.

My husband, and me booked two tours with Urban walks -Ruins and Bars, and Budapest Urban Walk. By coincidence we were the only ones taking the group tours on that day so it was like a private tour! We really appreciate that Urban Walks did not charge us extra and still gave us a great time. The pick ups, the drop off, schedules, etc went so smoothly.These walks were definitely the highlight of our trip!
Reka was our guide for the Budapest Urban Walk. She is so passionate about her city. She gave us a wonderful insight into the history of Budapest, also told us a lot of fun titbits. We had an amazing coffee and pastry stop in between the tour We went back there twice!). Before we knew it 4 hours were up! We were sad to see her go! Also Reka gave us recommendations to superb restaurants, cafes, even baths (we did gellert) and cruises (legenda evening cruise). It's like she had our back throughout the trip.
Our guide for the Ruins and Bars tour was Andrew. He was so much fun and easy to be with. He took us to unique bars that only a local would know. We had amazing crafted beers, liquors, food (must try Langos) and conversation! Egeszegedre!
If anyone is looking for these kind of activities in Budapest just go with Urban Walks blindly, they are simply the best!
