BeCozy is right next to Zurich Oerlikon train station (one station away from the main Zurich train station), which makes it really convenient and easy to get to. Around the hotel are all the food and coffee and convenience shop options you will need.
Most interestingly, BeCozy has taken over the old Zurich Swissotel's premises, which shut down in mid-late November 2020, ostensibly due to the pandemic. Therefore, for much more affordable rates, you are essentially staying at former Swissotel franchise premises, with the rooms and some furnitures / fixtures which have been left behind.
As is clearly stated, BeCozy is a self check-in and pop-up hotel, so do not expect any concierge service or room service. However, if you know how to follow the clear instructions sent over email, it is really fuss-free, and one of the most affordable options you can get for a stay in Zurich (which is one of Europe's more expensive cities).
