I give this doctor's office four stars because it is a good "one stop medical shop" in Zurich, with…read morepretty good service from each doctor I've been to, and also from the receptionists. They have doctors specializing in family medicine, dermatology, gynecology, physical therapy, etc. I find their family medicine and dermatology services to be pretty good. I have seen great progress in my skin from seeing the dermatologist here to which many others didn't really take their time out to properly diagnose my allergies. They even have Saturday hours - a plus for Zurich! If your usual family doctor is not in, they will try their best to find another family doctor within this practice (there are several), so you never really have to worry about not being able to see a good doctor in an emergency.
The one strange thing is that you have to go through a whole "Sihlcity" shopping mall to get to this doctor's office. You have to take the elevator to the 3rd floor, and within this whole Sihlcity shopping mall there are a few restaurants/stores on the ground floor, supermarket/stores on the first floor, stores on the second floor, pet store/Media Markt (nearby the doctor's office) on the third floor and Credit Suisse offices on the fourth floor. Pretty strange mix especially if you are very ill, trying to discreetly walk through this shopping mall to see your doctor!
