I do not understand how some one can not find an address in a well-planned city like Stockholm.
Who are traveling without a mobile phone in year 20012? if you have your own mobil phone so you can call from any public phone and reach the person you are seeking. In this case I believe the person does not live in this world and do not know how to do simple things like these, so it's not my fault, I did every thing I had to do.
So your bad experience are result of your bad planing.
Marcio was a very lovely and nice to have as a guest, always in a good mood and curious and nice to talk to! He was also a very respectful guest and I would definitely recommend to have him over.
