I stayed 2 nights here. Honestly, it is only a 3 star hotel. Reasons are 1) yes, it takes 5 mins walk to the train stop; however which is not the main crental stop. You would have to change at least 1 time to visit main attractions. From my 2 days experience, you would at least need 40 minutes to go out. 2) the sound proofing is very very very BAD. My neighbors were early birds. At 630am, I could tell what they were doing like flushing toilet, drying hair, even talking. I could hear every single words. 3) the hotel is not new AT ALL. I took this hotel mainly because I thought it's a new hotel. The truth is outside and inside of the hotel is ruined. The photos on website are 10 times better than in real.
If you want to sleep and take a good rest, trust me, do not choose this hotel.
