The experience with Felix and Iker was awesome right from the start when we booked and liaised with them. They were very helpful. They also greeted us and made us feel welcomed when we first arrived. They took the additional effort to guide us and recommend us good places to go to and good restaurants to try. They were very hospitable too. The room was private, spacious and clean. Loved how warm and lively the hosts were, Overall, they were the best hosts we had so far so we would highly recommend them to anyone who is visiting Vienna. :)
