Absolutely lovely apartment with lots of space and great views. Has everything you need for a short stay plus the bathroom is amazing! Apartment was so clean and really warm, which is exactly what you need in the Vienna winter.
Communication was good. Due to a misunderstanding about check in we arrived early but it was fine in the end. Key collection is via lockbox which is very convinient. Our only issue is that the cleaner let herself in uninvited on our second day and intruded on a friend while she was getting dressed - this is a bit of a security issue and needs looking into.
