I’m really sorry that this isn’t a great experience for you. Well, the pdf guide that I sent you has everything about location, traffic, Wi-Fi, keys. And really most guest can easily find the place exactly follow the guide as the house is just 2 minutes walk from the street and the guide has clear tips about where is the entrance of the lane, where to turn left, which is our room and so on.
About the phone number, I send you my number on the morning of the day you arrived and checked with your arrival that night. Other guest has successfully called me through this same phone number from bnb page. As I only has one phone number. I don’t understand why when you called, it says ‘none’ as well.
About the size, I think I have a very clear and highlighted tips on the Airbnb page saying that It’s only 14-15 square meters and tell you this again the day before your arrival. And the photos on Airbnb is taken by photographers hired by Airbnb and really is the same as the current situation of the house. So maybe next time you can take a close look at all the descriptions and photos of the house before you make an instant book~Still, sorry that it’s not a great experience for you~
