Me, my husband, my sister and my toddler (2.6 years old) stayed at Robin's and Olivia's apartment for 5 nights on our first Wienese experience. And we loved it. :)
Olivia was so friendly and nice, they both communicated promptly prior our arrival (and after) and were flexible. The apartment was spacious, clean, well-positioned, we had everything we needed in order to eat breakfast in the apartment (and sometimes take-away dinner too) and all in all was a great choice for us. So it is suitable even for small children :)
Thank you, Robin and Olivia.
