I visited Zürich for 3 weeks on business and Andrea was really helpful when I "checked in". She showed me everything from the apartment plus the storage and laundry room. She explained everything in detail as one would expect and was very very friendly and welcoming.
The whole apartment is very small but is big enough for a short stay especially very suitable for a single person. Its location is very very good. Nice neighbourhood with two major grocery stores just across the road. It's located just off an afternoon-lively square as there's Nordbrücke restaurant just beside it, city centre is in the walking distance, river Limmat with jogging routes and green park is even closer.
I would recommend this for a single person any day especially during warmer months when you have lighter and less clothes as this apartment offers very limited clothing storage space. But all in all I really liked it very much. Suited me perfectly.
