A few suggestions to reduce confusion for travel weary clients. Silly stuff, but when you are tired every little issue is stressful. The reservation was for unot D01. The sign on the building says D1. (Is it the same or will we look like we are breaking in?) The doorway is very dark hard to read the cpherlock keypad. The instructions did not say to enter the code flowed by pressing "checkmark." Add to fears we were at the wrong unit. After we got in, everything was great!
