Upon my arrival to Vienna, Dan provided me with information regarding my stay along with his phone number in order to contact him if I needed any assistance or had questions. Once I arrived in Vienna, I contacted Dan to ask him a question regarding my stay and he did not answer the phone. I contacted him again an hour later and he did not pick up once again. On my 3rd attempt he finally answered only to ask me why I am bothering him. Turns out he ignored both of my calls and when he did pick up, he was abrupt, rude and spoke to me in the most disrespectful manner. His customer service was terrible and he made my first couple hours in Vienna absolutely dreadful until I found a different host. Absolutely would not recommend Dan as a host.
