The place was very clean, and close to the train. You could walk everywhere (20-45min) for the main attractions. The East side gallery is about 75 min, but I love to walk so it was no problem. You could also take the train which is much faster.
After receiving the check-in instructions two days ahead of check-in, I never received another message from the host, even when I asked a question. I had no issues at all, but hosts in the past have always been very helpful with tips and answers regarding their city, so this was a bit different for me!
