I have stayed there three times and loved it everytime! It has become my fav Zurich hotel. It feels luxurious yet relaxing, the room hardware is great, service very nice, I like the design. Very international guest crowd. Some may be bothered with the location not being in the city centre but I love the relaxed location next to Uetlisberg where you can trek around and even use the train to get downtown. They offer a regular comp shuttle service to/from Boersenstrasse during the day though. Love their breakfast buffet. My biggest draw during spring/summer is the outdoor pool and bar. Its location feels very calming and resort-like, i.e. excellent for a short weekend break. A luxurious place for great relaxation. Never tried Ecco though.
