I had a great time on the Real SF Tour. It was a little warmer than normal for the time of year, but I had planned ahead and brought two bottles of water. Sean was our tour guide and was very knowledgeable about the different parts of the city and quite patient when the group asked lots of questions. It was also nice meeting the other people on the tour who were from all around the world. If this is your first time in San Francsico I highly recommend taking this tour to get to know the different areas. Be prepared for plenty of walking and some of it uphill. Comfortable shoes are a must!
