The really disappointing thing is that the hotel doesn't have staffs on site which means you will resolve your issues somehow yourself. I believe HOTELS.COM should indicate it clearly BOFORE the room is booked. I wouldn't book a hotel with no staff on site. What issues you could meet.
-You will need to submit the copy of your passport a few days BEFORE arrival. I wasn't comfortable to send a copy of my passport somewhere.
- When you have submitted all required paperwork, nothing happens. You will receive an email where it is said that a code for the building and your room will be sent a day before your arrival. What, if you could not connect to internet and receive the code?
- When I arrived, a nice person held a building door for me, and my code for room door did not work. Do you remember, there were nobody to ask for a new code? The problem was resolved by using button "open door" in the email but again, why the internet access should be required for the hotel?!
- There is no way to get an extra blanket or pillow if you need it.
Beyond that, the hotel was pretty good. The room was pretty good, modern and clean. The lock was a bit shaky but it worked when i pushed the door. Bed was comfortable but blanket was small even for me (I am average). Location is good - it is next to the train so it would be easy to get to/from airport or other city. Also, the hotel is not too far from historical places.
