Our stay at Ella’s apartment was great. The location is perfect, it is close enough to all museums and remarkable places, many cafes are just around the corner. The apartment looked exactly like on photos, the kitchen was very well equipped (even there was milk for coffee machine!). However the road repair right in front of the windows was not letting us to sleep after 7am, and loud neighbors were listening to music and shouted until 1-2am.
Though I totally recommend this place and Ella was very friendly and understanding. We loved our stay at Vienna.
