Sorell Hotel Rex
This no-nonsense base in Zürich has modern interiors accented in the brand's signature plum color and a convenient location for visiting the universities. Rooms come with box-spring beds and coffee machines, but not all have air-conditioning—a point to check if you're booking for the summer. Zürich main station is within walking distance, a journey made quicker by heading three stops north on Tram 7 or 15 to Central. It has no restaurant, but snacks are available.
