Kiki's home is light, sunny, and located in a delightful part of Vienna. The apartment was immaculately clean, from its cute little bathroom, to its tiny wee kitchen. Big windows open out to let in fresh air (I stayed in late summer), and double windows close to keep the street noise out for sleeping. The bed is large and firm for those of us who appreciate back support! It is up several flights of stairs which can be a bit enervating, but if you have a small suitcase it won't be too onerous.
The apartment is located right across the road from the tram stop, so it's super convenient. The neighbourhood was friendly and felt very safe (I walked him at night a couple of times). It's close enough to the Museum Quarter or the Belvedere to walk in 20 mins also.
I would highly recommend this apartment to fellow AirBnB travellers who want to stay in beautiful Vienna.
