Felix and Iker were great hosts. Their place was as described and very clean and tidy. They had all sorts of maps and information to share about the city. Felix recommended great places to eat and visit that were away from the touristy spots and even wrote things down on the maps for me. They were prompt and courteous in answering messages. I felt like I was visiting old friends I hadn't seen in awhile. I highly recommend staying with and will definitely stay with them again if I'm in Vienna!
