2 nights last week. Chose this because it's close to the gallery hosting an exhibition I wanted to see and also because it's right on the water.
Nice hotel with some very attractive design features. They seemed up to speed with SPG and were welcoming in that regard ( albeit to the extent of their participation).
Platinum breakfast is not a benefit ( 500 points is the default) but breakfast is offered at a discounted rate of € 20 via a pre-arrival email, probably to all guests.I took it and it was worth it: not a huge range but extremely high quality.
Pleasant place and I shall return.
