So, there's four of us going to Berlin, July 11 - 14. My son has been there and wants to stay near Unter den Linden - what area is that exactly? I've booked Meininger Hotel Berlin Mitte on Oranienburger Stra?e, but I'm worried about it. It was inexpensive and realize we won't be in our room(s) much but want to have a comfortable/safe area to stay. We have one room for the four of us, but I would consider getting two rooms, someplace, if the price wasn't outrageous. I'm thinking I should be able to get a room for the four of us or two rooms for less than $600.00 - that's my budget. Any suggestions? Thanks!
