Very happy with our stay! The apartment is spacious, spotlessly clean, nicely furnished, warm, comfortable and well equipped. Great location - quiet neighbourhood with a supermarket round the corner, only a 3 minute walk to the Naschmarkt, and the Kettenbruckengasse underground stop, which is just one stop away from Karlsplatz. Good communications with Martha, who was very accommodating about check-out time and letting us leave luggage there 'til later in the day. Our check-in host, Emil, was friendly, helpful and had great English.
