I booked this apartment for two collaborators of mine for a long stay in Vienna. They were very happy, Nikolai has been a great host and the apartment provide a comfy environment at a great location. Overall, a great stay! That said, there's one thing that could be improved and that's the lack of a proper bathroom (for clarity, toilet is in a separated room, but there's no bathroom, so the shower is in the kitchen). I think this is not a big deal for a couple and/or for short stays, but for longer stays it may not be ideal. At any rate, thanks Nikolai for a lovely stay at your apartment!
