This is the great apartment, which has a great location, within walking distance of the city center. Many different cafes on Naschmarkt (near the apartment) worked even during Christmas.
A bit noisy, for sure, but it was not a problem in the cold season.
There are just one toilet and one bathroom (without a second toilet) in the apartment, so it was a bit busy for 4+ people.
The communications and self-check-in process were excellent, any problems.
Recommend!
