9.4/10 Exceptional! (107 reviews)
Great property. Wonderful staff. Very clean rooms. It was quite noisy at night from within the hotel which was a distraction. Also, the beds are much too hard for anyone with back issues. Finally, the toilets in the basement should have toilet seats to accommodate travellers from around the world. Thank you!

The room was decent but it seems like there was no sound insulation. I could hear people in the corridor very loudly at 6-7 AM. The sliding door for the bathroom left a big gap (4-5 cm) which can be an issue if you're sharing the room with someone. Great location though.
