Me and my boyfriend stayed in Hannelore's apartment for a week and we really enjoyed it - the place has everything you need for short- and long-term stays, including a washing machine and a hairdryer. Super clean, cozy and stylish. The location is also great, as it is close to a U3 metro line as well as the tram no. 18 - both can take you to the city center/ train station very quickly, which is very useful as it is worth using the trains to see places around Vienna. Hannelore was very quick and helpful with all my questions and check-in was easy. All in all, I can totally recommend this apartment.
