Had a good stay at this central Vienna apartment despite a few niggles including no loo roll and the heating was constantly on high (we couldn't get it to turn off!). Communication and the check in process wasn't great - a few of my messages went unanswered when I asked about an early check in and we were eventually told that it would be 10 euros per HOUR which is ridiculous. Worth bearing in mind that this apartment is not run by 'Mike', it's run by a company called Sky9 City Apartments, so if you'd prefer a more personal experience, this won't be it!
