Good points: very clean, comfortable, easy to access and very well located in a quiet residential neighborhood. Public transportation is at 5mn walk. Tania's explanatons for accessing the apartment are clear, as well as for maintenance, internet and parkings.
Bad points: no cleaning products (or we didn't find them) for cleaning the dishes (by hand or dishwasher), the bath tub and sinks and not enough personal soap (just one tiny little bar for 2). Very poor insulation between the bathroom and the restaurant underneath. Restaurant customers were very loud until 2:00AM both nights! A welcome gift would be nice too:) And finally we found that 80.-CHF for cleaning is quite expensive compared to other places, since we tried to keep the apartment as clean as possible. Other than these few observations to help make the stay of future guests more agreeable, Tania's apartment was perfect for our stay in Zurich. Thank you!
