Teo and Otto's flat is eclectic and in a fantastic location, loads of restaurants cafes and bars nearby with metro just around the corner. Communication was excellent, met both Teo and his girlfriend Silvia who are super friendly, cosmopolitan and gave good tips on Vienna! We also left something behind and Teo was really nice about coming back to the flat to let us back in to collect it as he was out, we really appreciate that! Only thing to note about the flat is that the beds are at loft level so you need to climb ladders to access them, which may not be ideal for infants and those less mobile. In short, we had a great stay as 4 friends exploring Vienna :)
