This was a very disappointing experience. The fridge in this apartment does not actually work. This made the kitchen essentially useless as we had no way of storing groceries and leftovers. We informed Harry but the fridge was never fixed or replaced. Other recent reviews have mentioned this issue as well which makes me question the honesty of including a full kitchen in the listing.
The standing fan was also broken. Again, we informed Harry as soon as we noticed. He sent back a vague response but never replaced it. After one night in the very hot and stuffy apartment we ended up buying our own fan for 30 euro as it was unbearable to be in there without a fan.
There were also a number of smaller problems - no top sheets on the bed (only duvets, which isn't useful in summer), a broken lamp, broken hairdryer, dead batteries in the TV remote. All of these things made us feel like there is very little care put into the apartment.
Communication with Harry was OK, and a staff member was there to check us in at the agreed time, but I had to message him twice before I got a straight answer about check-in, and his responses were sometimes slow and vague.
The apartment itself is well-located, there's a supermarket very close and it's close to parks, public transport, and central Vienna. However, we felt so disappointed with the dishonesty of having multiple broken appliances and no attempt to fix the problem - we would not stay here again and would not encourage others to.
