We really enjoyed our stay. The flat was clean and comfortable. Check-in instructions were clear and easy and we were able to check-in late when we landed in Vienna. Yan had been really thoughtful with the amenities including guest slippers, curling tongs etc. Bed was really comfortable. Located next to the park - we hired the 'Lime' scooters that are dotted around so that we could whizz through the park/ to the station (would highly recommend).
