The first thing to comment on is location. The hotel is literally a stone's throw away from Grindelwald station. This is incredibly convenient for a variety of reasons.
The next thing to comment on is the view. The view from my balcony was something that can be best described as majestic. It's difficult to find fault with much when you can wake to a view like that every morning.
Excluding the view and in the interests of balance I am going to try and be as harsh as possible. Though these are very minor issues. It's arguable that the room safe could have been a bigger one. To allow safe storage of my laptop for example. Though I felt very secure in the hotel and I was able to put everything else I needed to in the safe provided.
Other than that (and I've been trying really hard to come up with criticism), maybe there could have been more toiletries in the room. In the sense that for shampoo and soap there was one brand of green tea body wash available. This is probably being very harsh though.
The dry sauna, though small was one of the best suana's I've been in. Assuming you want a really strong sauna. The steam room was good. The low infrared chamber that's available was a revelation and the jacuzzi was well maintained.
If I at any point had any questions, over transport or travel or anything in general, the staff were warm welcoming and approachable.
In conclusion, I would definitely stay here again. It was (and would be) a pleasure.
