We enjoyed our stay at Caroline’s apartment. The decor is wonderful and the location is very convenient, in a very elegant neighbourhood just a short walk away from the centre and 2 minutes away from the amazing Belvedere palace. The apartment was clean and there were no troubles coordinating with the host.
Only one small thing to note: we were given only one toilet paper roll for the whole weekend stay... and apparently supermarkets in Vienna don’t sell it on Sundays! Make sure to bring tissues with you...
