Best possible hotel in Zurich”

Switzerland can be expensive but if you are in Montana you can take care of few things within the hotel cost. They have excellent rooms, very comfortable along with nice breakfast and an ample supply of apples which can be consumed anytime. The breakfast spread is good and can keep you going for hours. The location is at stone throwing distance from both Zürich HBF and Zürich ZOB, so no extra cost needed for commute. It is also very close to the heart of Zürich old city. They have a spacious luggage storing facility, which I found super helpful as we had to checkout and go for a day trip to Lucerne and take a train afterwards to Paris. The lady at the reception during afternoon is very helpful and gets you checked in in no time. Overall an excellent hotel to be in while you are in Zurich.

Perfect hotel near Zurich HB”

Pros: - close to Zurich HB (if coming by train) and bus station (if coming by bus or joining bus tours) - excellent breakfast although it didn't change during our 5 night stay but we didn't mind really. there were a lot of options with rice, bacon, eggs, sausages, breads, yogurt and many more! - staff are generally nice and helpful - very clean - we were placed in the newly renovated wing and it was really beautiful, looked like a boutique hotel Cons: - nothing really! highly recommended

Chic Vintage Hotel”

Nice location very near to Zurich HB main train station yet in a quiet neighborhood. About 5 minutes walk. There are some restaurants within walking distance even we arrived at 10pm but no problem finding food. The location might be a bit away from tourist attractions but it was fine for us. Zurich is not too big and a walkable city. Our booking included free breakfast. It was in a nice and cozy space. Breakfast was basic but good enough for us. It includes scrambled eggs, hard boiled eggs, sausage, bacon, fried rice, cold cuts, salad, cereal, breads, coffee, tea, & juice. Room comes with Nespresso machine, safe, and Dyson cooler/ heater. We booked for Double bed but it’s more like 2 single beds combined. A bit smaller than usual King size bed. All in all, I would stay here again if I return to Zurich.

Too noisy!”

The only good thing about this hotel is the location as it is just metres away from the main station (Zürich HB). You can walk easily to the city centre as well as old town. Restaurants, shops, cafes, supermarkets are all within reach. Other than that this hotel is very noisy. Walls are way too thin that you can hear food steps, slamming doors and people talking on both sides of your room as if that they’re in your room. Not recommended for people who wants to have a good night sleep. I have to bang the wall twice for my neighbour to stop talking loudly at 1.30am…ridiculous! Room is pretty small with an awkward layout of wardrobe.
