Location is very central, the 11 and 31 train are literally within walking steps from the doors.
Bedrooms and Bathrooms were very well maintained and the bathrooms have a tankless water heater (that is awesome)
Never got a chance to get in the sauna (too many kids to enjoy)
Workout equipment as much as it was nice to see, it wasn't necessarily easily usable..just get out and walk if you want some exercise.
Rooftop views and atmosphere are idyllic for reading, movies, or just sitting there contemplating next steps in life.
Stairs--97 of them, bringing luggage up was a beast. Those with elderly parents or people with issues breathing, will have trouble getting up and down from the penthouse, I would not recommend this place.
Kitchen--all the cookware is there for cooking, the COOP and Migros are a two block walk from there where you can get food. Joy (personal side note)--it costs money to buy plastic bags!! Bring something to carry your stuff back in to the house. Mistake the first time, second time, brought my backpack (maybe Joy reads this and leaves the next people some sacks they can use to sack the food and bring back to the house)
Upstairs--there is a second floor and a third one to the rooftop, for those with big feet like myself, take precaution as the steps are narrow
Honestly, the place is fantastic and we had a blast!
