The apartment of Estrella and Gerald is quite conveniently located, six seven minutes of walk to Wien Mitte, very close to cafe, restaurants and supermarkets. Safe neighborhood, didn’t notice any problem even when I arrived close to midnight by myself. The apartment itself is clean and tidy, with basic equipments available. Check in is easy. Overall I am pretty happy with the stay. Only thing is that the check out time is a bit on the earlier side (10AM). It was clearly communicated in advance though. Should not be a problem if you are an early bird (not me 😂) or if you do some good time planning 😜
