Me and my two colleagues/friends stayed at Chihui's place for 4 nights for a conference and to sightsee Vienna and had the most wonderful time. The apartment is situated next to the Vienna/Austrian Conference Center (only a 5 minute walk by foot) and very close to the metro-station (5 minute walk by foot, U1 goes downtown and to the main trainstation every 4 minutes). It is a very spacious, clean and comfortable apartment with everything you could need for (dishwasher, washing machine, hairdryer, two bathrooms, Nespresso coffee maker and foam maker, ...), towels and bed linens are complentary and Chihui is very sweet in offering shampoo, shower gel, tissues, etc. for your free use. It was always very easy to get in touch with her. We would stay there every time again. Thank you Chihui!
