The apartment is VERY nice and perfectly situated. Samuel, the host is extremely responsive and helpful.
The self-check-in is organized perfectly, too.
So, summarized I can strongly recommend the apartment!
One little minus I do not want to hide, which had some room for improvement, which is the cleanliness. But maybe this was due to the EXTREMELY short notice between our booking and show-up (less than an hour).
All in all: 5 stars!
