Even though I paid online for the room already, while check-in the front desk asked me to pay the outstanding amount, which I didn't. The problem was resolved the next day when another person at the front desk was taking a look.
The towels had a huge stain on it as well as on the bed cover. It's definitely not up to a 4 star standard.
Moreover, I was freezing for both nights. The heater in the room is super small and not sufficient for the room since also the walls and windows are not insulated, the heat just escaped rapidly. Even asking for an additional heater on the second day didn't help much. I had already put on multiple layers of clothes and it just was unbearable. My room was additionally onto the street, making it very loud. Overall, I definitely can not recommend this hotel.
