Response from Alexandre:
Actually, we would have been on-time, if the number of the building had been displayed. 1 hour to wander around in the street, trying to find out a solution. Regarding the "second guest", I did a mistake whilst booking online, and informed you by email and we agreed on a solution, 1 week before our arrival. Paying the difference in cash did not seem to bother our host!
Conclusion: this experience at such a dirty place, moreover difficult to localize and with a hysteric host, yelling out for our late arrival due to our difficulty to access to the building, is afterwards good to get => beware of the people and of the places to be rented, otherwise bad outcomes can araise ;)
Not recommended :)
