Roman's apartment is exactly as it seems in the pics, and is beautifully coordinated design-wise, very clean (seemingly un-lived in!), with good wifi and coffee machine. And really close to the centre of Vienna and closer still to fantastic cafes and restaurants in the Karmelitermarkt area (we particularly liked Gasthaus Schöne Perle on Große Pfarrgasse - which was recommended by Roman). We didn't meet Roman but he was welcoming at the beginning via text/email. Two observations: the house is full of mirrors on every wall, and earplugs are recommended for light sleepers who want to keep windows open in the summer months (and sleep in in the morning).
