Very solid “3 star” hotel located in a very central location.
Hotel Adler is “3 stars” but everything considered, as good as if not better than other 4 star hotels in European capitals.
The location is in a cute location in old town by Central station and the University of Zurich. Very easy to get to and from airport from here and is a very nice location to walk around and explore Zurich from.
Room itself was kind of small but was clean and comfortable.
What’s great is also the restaurant Swiss Chuchi at the bottom of the hotel. It serves the breakfast if included (which was pretty good. Standard pastries/bread as well as cold cuts, eggs, fruits, etc.) and highly recommend visiting for actual restaurant meal service which includes the famous fondue.
