I'm heading to Warsaw in the end of April with my family. Looking for a good walking tour to explore the city one afternoon. Something informative to give us a good overview of the history and sites. We'd prefer something under four hours and don't mind paying a little for it. I know the "free" tours are pretty hit and miss so we would like something a step up from that! I'm sure this has probably already been discussed on here but I couldn't find any with recommendations for actual tours. Feel free to just send a link to any discussions on this! Thanks for you help!!
