Had a wonderful stay at Tuan Anh's place. The apartment is large, very quiet, and well appointed with lots of open space at the same time. The bed is very comfortable, the extra room perfect for work or home work out (brought my yoga mat and had plenty of space), and the living/dining room is inviting and comfortable as well. The kitchen is well appointed, bathrooms clean with towels and amenities. Additional bonus was being able to use the washer/dryer in the basement! And the welcome chocolates are sweet touch!
Location is also great, in short walking distance from various grocery stores, bakeries, etc. as well as several tram and bus lines, which makes getting around Zurich very easy.
Overall an excellent stay, highly recommend and would happily stay there again.
