For a medium-size hotel, this has quite a 'family-run' feel to it. And that's it's strength and weakness.
On the down-side we couldn't get a meal at 9pm and when we did get a set meal the next night, though superb and lavish, the six or seven courses meant we couldn't eat again for days. The room, and the hotel generally, seemed to have been recently decorated and designed by someone not from Milan. You realise how even operators of cheap chains get the edge in this respect.
The only rooms worth having are the Eiger View ones and with that sight (and the balcony) it seems churlish to criticise, but they don't quite have the feel of a top-notch hotel. And the mountain view is slightly spoilt by the main road right in front, though it's several floors below, especially if you get a high room.
The outdoor hot tub is lots of fun and the connected pool is pleasant and not small. The terrace is a wonderful place to sit with a drink pretending to have spent the day walking in the mountains.
Although handily located five minutes from Grindelwald Station, it's the 'wrong' way so you may have trouble finding it and the nightspots (if only) of Grindelwald are ten to fifteen minutes away, back past the station.
By the end of our short stay we felt like we knew the staff personally. They went out of their way to be helpful, from the welcome drink to the friendly departure. This is the sort of place that must have regular visitors from around the world. It would be unfair to say older people would enjoy this most. But just don't say 'boutique'.
