Communication is quick and the check-in/out procedure very easy.
While the flat is in a really good spot, 5 mins from Stephanplatz on foot, it's not great. It's a studio for 2 people only. There is a very limited kitchen (2 forks...) and the sofa is extremelly uncomfortable and it's not a convertible. The bed, while confortable, cracks very loudly. The place was clean. The shower has no pressure and needs to be fixed.
Unfortunately, the wifi is not what is advertised. It's barely there (2 bars) and it disconnects frequently.
This is a place to sleep, and that's it. It feels too expensive for what it is.
