From outside it doesn’t look nice at all but we knew that already having looked the location on Google maps, didn’t help the fact that the entrance door doesn’t close which is a serious matter ( should be a temporary problem). The inside is nice but more attention to “details” wouldn’t hurt (cobwebs and spiders on the door of the apartment and also (without spiders) on the curtains, only half a roll of toilet paper inside the apartment ( but then she told us where to get it), just two big towels, dirty glasses that we had to clean ourselves..
It’s not in the best neighbourhood (for example at night there’s almost nobody on the streets and you don’t feel very safe) but for sure it is connected well so I would still recommend it considering the price (which is not that cheap either but for Vienna it is a good price).
