Ralf is very responsive on Whatsapp and the place is beautiful. It’s cozy, and modern, and though each room is a tad small, there is plenty of space and the views are amazing. It must be absolutely spectacular to grill there in the summer! The apartment is well stocked with everything you need, and the person who showed it to me was professional. I recommend giving all passport / ID details immediately when booking, since the doorman downstairs needs them to check you in. It’s an open lobby, and any delays could leave you waiting in the cold.
