Recommend! Super clean, plenty of room, very fast internet if you're working, and an ideal location. Felix's place is walkable to the regular tourist sites while still in a great neighborhood. Place was plenty big for 4 of us. Terrific hosts -- fast communication and Felix was super flexible about a specific check in/check out situation when he didn't have to be. I hope to get back to Vienna one day soon. We'd be happy to stay here again.
