I am back to planning our trip this September. We (family of three adults) have settled on Berlin, Prague and Barcelona. I am looking for recommendations for a good private guide for walking and/or driving tours in Berlin. With this new forum, every time I type "Berlin guide" in the search bar, it comes up with zero?? Thus, this question which I know has been asked before but was unable to link to previous answers. So, please let me know if you have experience with a good guide/company as well as any recommendations for top sights. We will most definitely be seeing Museum Island, the Reichstag and a day trip to Potsdam. I feel a little overwhelmed trying to time all the sights and prioritize them. We will be in Berlin for 5 nights, four and a half days and love art, history and architecture as well as wine and food (one vegetarian in the group, we'll see how this goes). I DO have RS book on Berlin but still would like your expert experience/advice to add to this information. Thank you in advance!
