This was the fourth time in an apartment of Eva & Michi, second time in this apartment.
As always, it was very clean, all necessary equipment if you wan't to prepare food yourself were there (didn't use them though), the rooms are light and very spacious, the communication went flawless, the check-in was flexible. The apartment is just 10 to 15 min walk from the city center or less than 5min from public transport (which you don't need for most things here in Vienna when starting from this location). I would recommend this apartment to everyone and I'll certainly go back myself in the future.
